A couple...
after the FIL died, & left my wife & I to "manage" his collection, I traded off a vintage Hi Power, as IMO, it didn't fit in the collection all that well... he was big into BRNO rifles & CZ handguns... I wish I had that one back...
also in that collection was a pair of Norinco semi autos, one in 9mm & one in 7.62 X 25... they weren't worth much in trade, & both functioned good... probably should have kept them as well ???
over all I think long & hard before parting with anything gun related
funny thing, FIL was well know locally as a collector, Me, not so much, but after I got the walk in gun safe room done, & was able to hang on the walls & display, I noticed I have more than twice what he had, even taking into account the ones I traded in
... shows I hate getting rid of any of them... guess he picked a good candidate to "grow" his collection...
