i don't have anything too ancient, but i do have one of the first remington 760s that was ever produced. they start at serial #4000, mine is a couple hundred above that one. it was my late father in law's, and had been sitting in my mother in law's basement for about 20 years.

i shot a box of ammo through the thing when i got it and decided it was more of a wall hanger, it's pretty beat and the lack of a recoil pad combined with a narrow butt makes it one of the nastiest kicking rifles i've owned (and i own and shoot a .375 ruger).

i've also got a couple old model 99 savages, in .358 and .250, now, those are the ones that go out in the field with me
