My oldest is a 1884 Trapdoor Springfield made in 1885, excellent condition and still a good shooter. You didn't ask but my second oldest is a 94 Winchester .32-40 made in 1897. Next is a muzzle loader that was owned by my wife's grandfather from about 1910. Then a Winchester 1892 .44-40 saddle ring carbine made in 1929 and model 64 .30-30 carbine made in 1935.
Springfield 1884 45-70 Trapdoor that is dated 1889.
W.C Scott 10 ga double barrel fowling piece that dates late 1880's
Luger DWM 1917
Smith & Wesson model 1917 45 revolver made 1st yr of manufacture.
I have a Marlin 1902 12ga pump given to my great grandfather by the owner of Oskosh Overall, where my great grandfather was a salesman. My great grandfather was a clothing salesman in the Columbia City area and would take the owner of Oskosh rabbit hunting when he came down from Wisconsin on the train. The old Marlin has no real antique value ($65) so I had it restored and it looks like new.
My oldest gun - Ward's Pump 16 ga. shotgun inherited from my father. It's a heavy gun but I had fun blasting rabbits with it in my younger days. I ought to have it restored. This is interesting thread to me. I wonder what stories all these prizes could tell.
