Thank you canvasback...I'm still a little gun shy about posting here...Do you think Flues was maybe trying to tweak the Ideal lock up? This gun was about the time of the James Packard gun (commissioned)I've not seen this gun...and a decade ish before the Tom Mix gun...(Winchester museum, again, I've not seen the Mix gun either) ...so I don't know if there are other rising bite Flues guns out there...I know of one other...or did it change hands and maybe it's the same gun
