Need Info on a rare Lee Enfield No4 Mk1 POL OLD

[Beerhunter]

I" The grooved upper handguard, the ROUND cocking-piece and the actual Bolt-head Release all are pointers toward a very early rifle. All of these features disappeared in the rush in WW2. They were part of the design, but these parts were done away with because they took time and money. The grooves in the handguard just were not cut: faster and cheaper and easier to finish. The ROUND Cocking-piece was replaced by the faster-to-make and cheaper flat Cocking-piece. The right side of the Body (Receiver) got a CUT for releasing the Bolt-head and the Screw and Spring-catch were done away with, along with the time to machine them. Early rifles are SCARCE.

But your rifle does not have the early round cocking piece but rather the later cocking piece. Additionally, the bolt release was never changed on UK production rifles (No.4 Mk.1 - which is what you have), only North American production (No.4 Mk.1*).

BTW, the ejector screw is missing.
