So I took a chance on one of these from eBay but I've not had much luck finding info about these pens. Is there anyone on the board that bought one of these? If so, how do you like it?
Nemo will probably pop in an ID this for you sometime. In the meantime, I found a long discussion in the FPN archives that suggests that it might be made by Reform.
I don't know anything about these, I've never held one or seen one in person. I have noticed it being similar to some Geha pens I have from the '50s and early '60s, looks like an ERO too, also shaped a lot like Reform and Senator pens since there was a lot of copying going on then by smaller German manufacturers. I saw the eBay listing and the seller said it's from an area around southern Germany and Switzerland.
I recently found out about some Lindauer pens from the Bodensee area (southern Germany, Switzerland, Liechtenstein) that look very much like this pen. I'm currently researching these in what little spare time I have these days. Interesting pens to say the least. http://www.lindauer.li/schreibraritaeten-der-50er-jahre
