The AMT Hardballer was a late 1970's gun, back when all stainless 1911's were a lot more of a rarity, and I had one from the original Arcadia Machine Tool shop. The quality steadily dropped as they moved locations, and the location is listed on the gun. Think there's a Wikipedia article on them or something else. They are a pretty standard 1911, and the field strip is normal. Never done a detail strip on a 1911, so I wouldn't know about that, but I doubt the AMT is much different. They're not like the newer designs like a 50GI with it's reverse plug and stop pin in the recoil rod or the two piece, funky, and irritationg Springfield long slide. These are two piece barrels like older 1911's, with the back of the barrel and the locking lug heat fit to the turned cylindrical barrel, and the AMT's are NOT silver soldered in place. As such, you can tell how many rounds have been fired by the gun and it's proportional to the size of the gap between the rear outer part of the barrel and the rest of it.
Here's the reference, and it turns out the AMT Hardballer was the FIRST all stainless 1911 made. I held onto mine for 20 years, and it was my brush, chainsaw, and hiking gun because it was invulnerable to sweat, but I finally sold it to help but a Bright Stainless Colt Delta Elite.
