Lee Enfield 303 No.4 Mk. 2 (F) found on reciever Basic Review (RTI)

Another RTI sold to me unknowingly. Price was fair. Some range time at the end. Wanted to add a thumbnail. Found the model under sum gunk that I thought was cleaned off. Faded . Barely visible, using a toothbrush and mineral spirits to reveal it. So far no 4 mk 2 (f)
