Thanks fellas. I'm attempting to compose info on as many Austrian/Bohemian/German makers as possible and post them via a web-page possibly with pics of the examples. I can take a few images of the Schuler or Simson and add them. Also, the G. Wilcke 2 barrel set was 8/10 not 10/12 and one or both were sourced from Belgium. 8 bore tubes are not common.

Buchsenman; your unknown maker drilling was probably made by Emil Funk. I have some info but just haven't had time to post it yet.

Kind Regards,

Raimey
