First Generation Universal Manual (7 MB PDF file) - Thanks to Jim at http://www.m1carbinesinc.com/carbine_universal.html for this great example of an early manual! Note there's extra technical detail and a primitive publishing style - it's not as marketing-oriented as the later manuals.
Second Generation Universal Manual (3 MB PDF file) - Early non-GI changes, like the 2 recoil springs and the new slide, but with a screw for the slide key.
The manual below is for third generation (non-USGI, with no screw for the slide) and beyond.
