L39A1 advice for a beginner if possible please.

[FlightRN]

Merry Christmas to All,
I was digging through the safe, paused and started looking at my L39A1 more closely. It was one that apparently was used by one of the RAF units stationed in Germany.

I had forgot about the markings stamped on the forward leg of the PH5C rear mount (where the ejector screw goes). Does anyone have an idea of what "RWF 3" stands for?

Of interest to me was that the "TARGET RIFLE ASSOCIATION" sticker used crossed L42A1's as the backdrop behind the RAF badge. Until today, I had not noticed this.

I don't remember a discussion about it but FYI- the front sight is Alfred J Parker manufactured.

Best Always,

Michael
