What you have is a mutt after wwii the brits used parts from bad rifles to put together good ones.
the receiver appears to be a maltby but the 4 digit serial is bsa Shirley . Maltbys have 5 digit serials. Usually bsa are marked m47c which I do not see the c. The serial block am could be either bsa or malty. Fortunately, your bolt matches the original serial. You have a mismatched magazine which is common, the 2 on the bolt head indicates probably at some point someone put a new bolt head on to cure headspace issues. Most were issued with a zero or one bolt head. The broad arrow found on several parts is a British military approval Mark. The upper band Mark is a savage s Mark, bayonet is long branch. Don't have time to look up the rest. Try milsurps.com enfield forum for the receiver and the rest. No offense but better pix will help.
