Since cheesy is on a plane for Utah, I went and looked up the info.It’s unmarked as far as maker. Some of the German gun gurus on some other forums said Sauer or Simson action then finished by others. I’d have to go find that post for the specifics. Fun little gun to carry all day.
They thought that the action was obtained as a rough forging from Sauer and finished by Oscar Will (Venus Gun Works), proofed in 1919. Krupp Steel barrels, joined by Max Morrow, Nitro proofed.
Once he gets it to a qualified smith for an action tear down and clean, some repair, and glass the stock head to the action to save the wood, it will be a real solid hunting gun.
