It is tough to Value these rifles. I did see a E1 with scope and and 8 round and 20 round mags go for $500.00. The 20 round mag is worth $100.00.
The A3 , A6,&A7 rifles are much nicer IMHO so should go for around $4-500, in original condition. With your rifle being refinished, it will lessen its value, usually by a fairly large amount. FS
