The thing is from the 1940s or even older. It is a piston fountain pen, the upper end is a rotary wheel over which a piston sucks through a negative pressure the ink in the filler. The cap is labeled on the edge with "14ct rolled gold" (money gold). Below is a photo of the pen in which a jumping goat and to the right of the image of the goat (presumably) a mountain can be seen, about a part of a circle.
Which manufacturer is this fountain pen? When and where was this fountain pen made? Is the spring completely from Iridium? I found nothing comparable even in Google and therefore ask once here, maybe someone here would be very happy.
Which manufacturer is this fountain pen? When and where was this fountain pen made?
This is any non-known fountain pen with a feather of the company "Bock" (see also answer from Wyooo ). They were used in a number of fountain pen. The age is not clear without further details.
But if I know that right, then that should have been around the 2nd WK somewhere, where the springs were pointed to the iridium. ("Iridium" lettering on the springs).
Is the spring completely from Iridium?
No, the spring is made of 14 carat gold. The "grain" at the top of the spring with which you write is made of iridium, a very hard metal. Whomn You would write on the "naked" golden feather, then the tip of the spring would wear out too fast. Therefore, a small drop of iridium is soldered to the tip. One thing that is no longer mentioned today at the fountain pens, as it is generally common today.
So I've come out again and followed
That could be of Senator. Someone in an English forum indicates that 2 German companies use this spring with the mountain goat
It could also be a Capricorn, then it would be a bock pen from Peter Bock in Heidelberg. Since the company only produces feathers and KA filler, unfortunately can not be closed on the manufacturer of the filler.
