Help with four 585 gold pens

[AcLondon]

 

 

I’d love some help identifying pens that I’ve just picked up. There are three fountain pens and one four colour pencil (possibly pen but I don’t think so).  They are all 585 gold. 

I can identify number 1 easily – it’s the reason I bought the lot.  It’s a Montblanc safety #2 overlay gold with white enamel star. 

#2 was sold as a Pelikan but I didn’t think it was in the listing and nothing lends itself to me thinking it’s a Pelikan now.  It’s nib is something like ‘Palias’ a knock off of a Pelican perhaps.  It appears to be a turning know filling pen.

#3 is a four colour ballpoint with ‘Kosca’ on it.  It is inscribed with a date in 1929. 

#4 is maybe most interesting.  It has no markingon it at all (other than 585 on the clip).  It has a ‘Iridium Point’ nib, I think made by Bock.  It looks and feels for all the world like a Montblanc safety from the late 1920s but nothing other than shape to suggest it. 

I’d love any guesses, info or help with identifying the last three here!

Thanks so much, AC

If there's any engraving on the cap bands, that could be helpful, as would full length shots of all the clips.

Nothing really. #4 has no markings at all other than the 585 and nib marking. Same with #2. They all came from same collection and the gold is in remarkable condition. The date in the pencil is 22 May 1929 amd I'd say that fits with the Montblanc pen era fairly precisely. Some more photos...

Of course I'd love to believe the unidentifiable one is Montblanc. Everything says Montblanc safety, except, well, any actual MB symbols! See comparison photo here.
