Interesting, Ralph. And thanks.
Do you have any idea what the 460 means? The HFT in question has a 360 on it, in addition to what looks like a three section date code that, if I'm reading it right, points to February 5, 1930.
I'm still working on some issues related to it, but I'm suspecting it was a first production run .22/32 Bekeart that later received a new barrel and extractor rod. The serial number is in the range of the first production guns, but the rod knob is of the later, barrel-shaped type. I believe it should have had the mushroom shaped knob originally. If it was serviced in 1930, it could have been given a new barrel and an up-to-date knob.
It is an interesting gun, but unfortunately, not for sale. I'm working with a client to sort out the mystery. I will instruct him to get a letter on it, if eventually I'm convinced it is a first production run example.
