I'm starting this restoration project on a No4 Mk1/2 and was wondering what I can learn about the history of the rifle from the markings on the rifle.

There are 2 model markings the older looking one, on the left side of the receiver plate under the rear site reads: No4MK1ROF(F)4/43
The newer looking one just forward of the first one reads: No4MK1/2(F)FTR
Just below that number is another number that reads: 752.CB24081A

The serial number on the left side of Butt stock receiver directly under the safety reads CB24081A

On the right side of the rifle just forward of the bolt says ENGLAND and below that is a makers mark (sideways crown below circle with I , looks like)

Any information is appreciated.
