LAMY cp1 time table

[SwourD]

Hi everyone! Just made an account to respond to this thread :) I started hunting CP1s down a while ago, their shape and clip type are very nice! I'll attach a picture of the ones I already have in case someone's interested; still looking for the white one and the metal with a black strip.

 

On my brushed finish model, the cap and body of the pen have noticeably different textures; I'm wondering if perhaps they stem from different pens. I'm not sure if you can tell the difference in textures in the photo. The body might even be from a LAMY st, which have a very similar shape - I have one and the cap is totally interchangeable with all of my CPs.

 

Thank you for compiling the table with dates! Tried making one myself a while ago, but it was far less complete than yours From what I've heard, the white one comes in two slightly different variations: the black "LAMY" text on the cap appears on different sides of the clip. Not sure if this is important enough to be added to the table though, I think they're still the same model.

Recently I found this pen on the Bay, it was advertised as a LAMY pre-CP1, model 19. With exception of clip, it seems to be identical to a second generation CP1 (9,5 mm diameter). Nib is unmarked. Body and cap made from glossy Alu etched with a nice chevron type design. Any information about what it is?

It's not a version of the CP1.  It is called the Lamy Linea (Model 49) with a herringbone (fish bone) pattern.  The same pen can be had with stripes (there is another thread discussing the model with stripes at the moment) or checks (square pattern).  It is very similar to the St, at least I think the feed sections are a direct swap.  This pattern/model also came in Black.

 

According to the information that I have the original version of the CP1 came out in 1974, the later revised version of the CP1 (fatter) came out in 1983.  The Lamy St came out in 1979 and the Linea came out in 1986.  So the Lines was the later of the three models to be produced.

Thanks, that makes sense. If the Linea came out in 1986, that was after the CP1 was revised and explains the the similarity to the CP1.

Only the ballpoint pen and the mechanical pencil of the cp1 series came out in 1974. The fountain pen came later in 1977.

Hi Christof,

 

thanks for clarifying that.  My mistake I was just working off a chart of dates for various Lamy Models and forgot that for the CP1 the fountain pen came out later.

 

Cheers,

Nice post !

I've got the brushed steel and the sterling silver models but don't know if it is 70's o 80's.

A very nice pen.

According to Christop's table on the first page, if you have a sterling silver one that is pre update in 1983 - so the thinner one.  If the brushed steel has the same diameter (can you swap caps) then that is also pre-1983.

I am trying to complete Christof's list with a bit more information. 

I am wondering something. I don't seem to be able to remove the feed from the older model CP1's. Did somebody manage to remove the feed from their older models?

Great thanks, Julian.

 

So I could guess now they are pre-1983.

 

Kind regards, Lionel

Darn!!!!  I have to admit I'm not brave enough to take pens apart in this way.  I have had some feeds come out the changing pens, but otherwise I leave well alone and enjoy the pictures from people who are braver than me to understand how these things work 🙂

Haha i shall not rest before i am able to fully dissasemble an old cp1. No clue what i did wrong here but i’ll definately give it another try with another pen some day  (maybe invest in some crypto first before doing so.. ) but firstly i’ll try to remove the feed of this broken pen (i cannot break it any further so violence is an option now ;))

 

i’ll share my progress here

The White version was made in the earlier/slimmer version.  In the attached picture the bottom three pens are of the earlier/slimmer type and the top two are the later/fatter type although it is difficult to see.

If you are ever thinking about selling the thin white one... please let me know

Lamy CP1 Timetable

21 January 2022

As a follow up of the topic of Christof¹ I tried to find out a bit more about the CP1 timetable. I do not claim to be entirely accurate but this is what I found and maybe we jointly can fill in the blanks. 

In addition to Christof’s post I used several sources to come up with this summary: ²,³,⁴

Model coding

All CP1 models share the number 5 in the model coding. It is prefixed or suffixed based on the pen type and finish respectively. Only the fountain pen does not have a prefix and therefore only has a 2 digit model coding where the others have a 3 digit code.

5X: Fountain pen
15X: Mechanical pencil
25X: Ballpoint
35X: Rollerball
45X: Multi color ballpoint
55X: Fineliner
65X: Twin pen ("Mehrsystemschreiber", ballpoint and mechanical pencil?) 6 is also used for tri-pen??

The X in the list above represents a finish for the pen. 

Color coding

0: Brushed Steel
1: White gold plated (???)
2: Silver plated
3: Silver (Sterling Silver 925, later replaced by Platinum finish)
4: Chrome plated (???)
5: Metallic (present in 1988 catalog)
6: Matte Black (post 1983 replacement of color 8)
7: White and black
8: Matte Black
9: Brushed Steel (post 1983 replacement of color 0)

?: Hematite / Gun metal / Glossy grey black

All CP1 models

Disclaimer: I only mention introductions, when a pen was already in production, they are not mentioned. I have no information about when a pen was discontinued.

1983 Model revisions

Around 1983 the model was redesigned. It got a tiny bit longer (about half a millimeter) but quite a bit thicker (about 1 millimeter). Nib and feed were adopted from the 1980 Safari model. The nib got a breather hole (yet, no markings on the nib as we do see nowadays). 

Another small change after 1983 - the feed (and nib?)

Not sure when but after a while the feed again was changed, maybe around a similar time the nibs got their markings (LAMY (585 14k) and Nib size). This did not result in a noticeable external change (measurements). Probably only the internal structure of the section was needed for this change. Why they changed it is not clear to me, I think it probably changed for all models at a certain time, maybe the new feed performed better. Any help on the time when this change happened and why this happened is very welcome.

Great work, will have a look and see if I can add any more detail.

 

As a point of interest I believe the initial code on the three digit code is consistent across the Lamy ranges so anything that starts with 2XX is a ballpoint, anything that starts 3XX is a rollerball and so on.

 

Cheers,

Julian

Yes indeed it is.

I have questions for the Lamy slim fountain pen specialists.

 

Three weeks ago I bought a cp1 (black version); although I tend to prefer the chucky, bulkier fountain pens, the cp1 charmed me and has been used daily ever since.

Today, by chance, I came across this fountain pen in a second-hand shop:

 

If I understand you correctly, it's not a cp1, but a Lamy Linea. Funnily enough, the grip section is exactly the same, even the sprue points for the injection moulding are in the same place, the caps are interchangeable and can also be posted to the other pen and the dimensions are completely the same. The hole for pressure compensation when opening and closing (under the clip) is also in exactly the same position.
Only the clip is different, even very different.

 

Was this pen launched before the cp1 or did both models exist in parallel? Does anyone know in which period the model with the squares was manufactured?
The Lamy lettering on the clip is quite worn, but otherwise the pen has no signs of wear.

 

Does anyone know if the aluminium box I bought it in today is contemporary to the pen or could have had nothing to do with it?
Questions about questions.... Thank you very much if anyone can give me any information!

 

Oh, one more thing unrelated to Lamy: I bought this blotter in the same shop, in black stone and brass, for a whole €4 (tax included). I'm at least as happy about it!
