lockbar or T105 in 1943...

[crowtalks]

I stumbled across a US Army training film from 1943 titled: "Rifle Marksmanship with the M1 Rifle - part 2" and a couple of things jumped out at me.

I thought lockbar sights came on the M1 in WWII, but the rifle in the film looks to have the T105 style...and the gas tube appeared to be in the white.

When did they start using the T105 sight?

were the gas tubes hard to parkerize? (I just thought mine had the finish worn off)

Gas cylinders (not "tubes" as in AR nomenclature) are stainless steel and prone to finish loss on a diligently cleaned GI rifle.

The flush nut rear sight, early design, looks a lot like the T105E1 postwar sight.

Ah...I didn't think about the flush-nut sight...I don't think I have ever seen one. I didn't know the gas cylinder was stainless steel...explains a lot...

Some G.I.s would darken their gas cylinders with smoke from a candle or Zippo lighter before a night patrol.

Winchester gas cylinders were copper plated than finished in the dark color

Winchester gas cylinders did not have the bevel on the bayonet stud - but often during rebuild the bevel was added

Here's my Springfield to show the difference, best pic I have for comparison...

Don't mean to hijack the thread, but regarding Winchester gas cylinders, would any experts be able to identify if the finish on this particular one is original? It's just not something I am adept at yet. I only to look for a Du-Lite finish but I don't even know if I'm properly understanding it.

Here's the one in question
