Dad's Kar98. Gustloff 1942 all matching, with sling, muzzle cap and some ammo. My uncle brought it back from WWII.
The first I bought myself? I had so many I can't really remember. The late 80's to 90's stuff was plentiful and inexpensive.
I had many 96 Swedes, 98's, Argentine, Peruvian, Turkish, Portuguese, and other Mausers, #4's, #5's (never a #1 though)
P-14's, a 1903 Springfield, a U.S. Krag, an M42b, AK's, FAL's 1910 Brownings, an Inglis Browning Hi Power, a couple S&W Mod 10's (Police surplus) and on and on, but I don't remember the first one I bought myself...
