parts identification help need.

[Light Infantry]

It has been a long time since i delved into these parts. I believe many of them are for a 1911. Any help would be appreciated.

Are both of these 1911 firing pins? If so, why the different profiler and why is one of them a lot smaller in diameter at the tip? Also what are some of the parts? (and yes, i know the 1 part is a rear site, lol)

No idea in the first pic but the 2nd pic clockwise from the top the parts are:
rear sight, ejector, hammer pin, plunger tube, mainspring housing pin retainer, ?? (could be a firing pin stop but I can't make it out from the pic), sear. Firing pin on the left is a 1911 (with spring) but the one on the right doesn't look like any 1911 firing pin I've ever seen.

The firing pin on the right is from a HiPower. The split rings in your first photo look like the ones from the original gas regulator on the C6.
