Here's my little contribution:
1893 Turk Mauser 8mm (really got it because it was only $100, and I thought the Arabic date and inscription was cool, and something a little different for my collection)
1900 M96 C.G. Swede Mauser-by far my best condition, most valuable, best shooting C&R.The pic really doesnt do it justice with how mint this thing is.
Minty Izhmesh aresenal Russian sks from 1954 (apparently only made there in '54 and '55, so thats kinda cool)
1943 Saginaw SG M1 Carbine (my dad was an engineer at Steering Gear in Saginaw where I grew up, for 30 years-not during WWII though)
