You aren't rude Steyr Man. To be honest, even thought the pistol only has 10% or less original finish, if the markings hadn't been defaced with the sharp edge of a file, I would never restore it. When they're butchered, the sky is the limit. Bear in mind the owner is a retired Army Colonel who wants a representative piece in mint condition and that's exactly what he'll get when complete.
Jim, I'll take some pictures when it comes back. The pandemic set Turnbull's back and the restoration will only begin this month. Hopefully, it'll be done by the end of the year.
