Ive talked the the Heym company about the gun. Their thoughts were it was made by Foerster with the help Of Heym, or a Heym associate as you mentioned. Their reasoning was Foerster most likely made it because his name is in 2 locations, and there are no other names on the gun. Does that sound correct? Or should I take the gun apart and look for evidence elsewhere on the gun?
When I break the gun over, engraved on one side is the crown over the U, and the numbers 124. On the other side is 2222 CH. Maybe the CH is Conrad Heym who wouldve been able to help Foerster?
