Gyvel may have nailed it, but he didn't nail my L-L M1917 and M1, which had a red (repeat, RED) stripe, no white, green, girlish pink, sexy violet, or anything else. And, again IIRC, the WO order said "red"; nothing about white.
As I said in my first post, I don't know what the marking on that 2A means, but simply mentioned what a similar marking meant at one time.
