I bought a Quackenbush first model rifle off a dealer quite a few years ago which was quite a good copy. and l sold it on to a collector of Quackenbush's
as a copy in 2019 at Kempton. he asked how long l had had it, as he had seen one exactly the same for sale not so long ago. but l had mine since 1996 so there are at least 2 of them out there.
