I happen to be adopted, but met my birth-mother and several siblings for the first time in 1988. A strange and convoluted tale ending with her locating me indirectly in 1986.
When my birth-grandfather died she gave me the Mauser Model of 1914 7.65mm pistol (replete with German military acceptance stamps and proofs) that his father had brought back from Belgium following WW I. Apparently the German soldier carrying it "no longer had any use for it" as the saying goes.
I was the only one of my siblings that had grown up around, and therefore had lifelong experience with, firearms of all types. So I guess I was the safe bet, and probably the only one interested.
The Mauser is in 90% plus condition and fully operational, and even though I have 2 boxes of 1960s vintage Remington ammo that came with it, I have yet to fire it. Call it a probably misplaced yet valid concern about 100 plus year old recoil and striker springs.
Cool old gun though!
And I'm still close to my siblings and birth-mother.
