Desk Pen Id

[PenFisher]

I got an odd-lot of pens and parts today and a Sheaffer desk pen with two tone FeatherTouch nib was included. I'm not well versed in Sheaffer models, filling systems, dating, etc.

 

Any help or comments would be appreciated. I did take it apart for cleaning and inspection and removed the stiff ink sac and it looks in pretty good shape overall. There is also a very small white dot towards the tail of the pen.

 

Is the metal cylinder that screws on over the section to accommodate the desk base?

 

What sac size is appropriate?

 

All help and comments are appreciated. Thanks

The pen would appear to be a TM TD Sovereign from ~'51 in which case a no.15 sac will fitl. It will most likely also need an o-ring replaced in the back end of the barrel. The metal bit is the inside of the tulip. The small WD you see is probably just some muck in a hole that helps the TD to work (assuming it's on the barrel), a WD model would have the WD on the tail piece and this model should not have one. There is an earlier TD model that takes a bigger sac (no.17).

Thanks of that information...much appreciated HH. I do see a small hole in the barrel that is clear. The WD is definitely a WD and it is on the tail piece. As for the metal cylinder ("inside of the tulip" as you mentioned -- am I correct in thinking then that when the pen is put into the base/tulip that it is screwed in to keep a somewhat air tight seal when not in use? Thanks

Yes, it screws in. The TM TD barrel is ~10mm if that helps. I'm suspecting a mix of parts or it's the earlier fatter model with a nib replacement ??
