Measure from the breech to the muzzle end; dimensions in inches are fine. I think I would contact Merkel in Germany directly. Jani might have some insight into the protocol. Is the proof date on the SxS an "1181" 1981 or "1191" 1991? There's also a lot of serial numbers between the 2 examples. Are both stamped Gebrüder Merkel? Also I thought that 447 series had the Model stamped either on the upper rib or triggerguard bow. Do you have an image of the steel types? The SxS have the Russian IZH 50A steel. Also I would search for a period Merkel catalogue. With the GECO(Gustav Genschow) stamp, I wonder what part that concern, or Dynamit Nobel Troisdorf, played?
Kind Regards,
