Montblanc Meisterstück 134 Fountain Pen
This 134 dates from the late 1940s to early 1950s. Its hard to date this one since it has the transitional cap rings. The clip and rings do have some brassing. It has a long window and is a really nice example of a pen about 70 years old.
It fills via telescopic Piston Filler. It has a fine semi flex nib.
