This hat maker was out of East Germany (Ernst Gierisch, Zwickau) .
I contacted the DE eBay seller and this is what he had to say. I will have to check back with him on the current situation.
Google translation.
"hello,
It is an ancient hatters and furriers (furrier) workshop, it was founded in 1887, all I have pictures on the ground was found in different chambers, there were produced until about 1960 hats and furs. I try this nice workshop closed for several weeks and sell it together but unfortunately this is not easy. It would be a shame to sell everything individually and tear apart. I'm still waiting for something then I have to go in the retail sale. 2 books in the small manufacturing concerns and care of fur.
salute to America,
regards uwe"
