I grew up with three generations of military people, history and milsurps were as commonplace as silverware or toolboxes (given the relative, sometimes those mixed together).
Then, one day, I got to trade an AMT Hardballer for a '42-dated Smith Corona M-1903A3 . . .
Which was the same week I had traded for an M-1936 Cartridge Belt, dated . . . 1942--score. Said belt now has a set of '42 suspenders, '42-dated field dressing carrier, even a '42 canteen carrier with a 1942 porcelain canteen--yeah, I've a touch of OCD about this sort of thing, and had bought, sold, and traded for much, much, more.
