Postwar Piston-Filler - But Which?

[sidthecat]

I bought this in a lot of three pens - a Reform and a Regie with a glass nib, but what's this? It's a deep Loden green and no markings I can see. It came with a gold Bock nib. Any ideas?

What kind of filling system? There have been zillions of no-name manufacturers using Bock nibs (at least in the 1950s). Could you post more pictures to get an idea what era this pen is from?

Here's another picture - there's not much information here.

What is the nib like?
