I forgot to mention that Greifelt had similar style side frame reinforcement and the longarm in question is also similar to the Greifelt Model 96(Model 94 w/ horn triggerguard bow). Both E. Schmidt & Habermann and Greifelt offered a clamshell action DR and pretty much used the same term "Stabil" so I don't know which came first or if E. Schmidt & Habermann was sourcing Greifelt for frames. Greifelt did offer offer a hammer version of the "Stabil" DR as a Model 258.
A Bernhard Merkel catalogue is purported to have surfaced and in it is a "Stabil" Model 11 Bernhard Merkel offering with Poldi Anticorro tubes, so I attach even more probability to Bernhard Merkel as the source of the filed clamshell frames, which may have been forged at Sauer. Now there is a .450 Sauer clamshell DR or 2 out there. Hopefully someone will find a frame stamp hidden by the wood or components.
Kind Regards,
