This Merkel #3921 was recently at auction and I was curious if anyone knows who picked it up. With the low serial number it just might be a BeMeSu(Bernhard Emil Merkel Suhl) example and tilt the scales in the muzzleshell frame filing being in his court. Can't tell for sure, but it does not seem to have a single set trigger.

Kind Regards,
