[QUOTE="Perplexed, post: 2363814, member: 7157"] It can be tough to identify the gas cylinder, since some swapping took place as a company ran out of GC's and another company sent them a batch, etc. It's also known that SA used the HRA tooling to manufacture several hundred thousand gas cylinders in the early 1960s for rebuilds. Having said that, HRA gas cylinders [I]tend[/I] to have a slightly oily-looking finish compared to the drier-looking postwar SA finish. Also, the punch mark in the center of the stacking swivel screw (on the opposite end from the screw head) on HRA's [I]usually[/I] is centered, while on SA GC's the punch mark is [I]usually[/I] off-set. As for the HRA trigger group, it's probable that it's not original to the rifle, but I wouldn't rush out to replace it just yet, as my sieve-like memory tells me there was some swapping of trigger housings taking place in the post-war period. If the TH is a different color than the rest of the metal, then it's likely it's not original, but if it's the same coloration and there's no evidence of a rebuild (additional P marks on the stock, etchings on the right-hand receiver leg, etc.) then it could well be original. Yes, I'm the same "Perplexed" as over there :wink2: [/QUOTE]
