Don't blaspheme me too much, but I had not owned a carbine until Friday night. Mostly I've collected German arms. I went to an auction Friday night to buy a particular luger. I was outbid on the luger but picked up an M1 and another gun. I'm trying to gauge whether I got ripped on the price of $475 or if it was a decent purchase. I'm going to list some of the identifying marks and hope to get some advice. Winchester s/n 5715748 under rear sight. Barrel is marked with a small "w" on top along with what appears to be a "WP" in a circle. Rear sight has an "H" within a shield. Trigger guard stamped with a "J". Safety is marked "EW" and mag release is marked "M". All above are in really nice condition with greyish-green patina. The stock is not original, it is in good shape but definately not GI. No bayonet lug but it came with a flash hider marked "hider-flash-m3-sa". My question is this, was the price decent and should I look at investing in an original stock? It shoots great but I don't want to invest too much if it isn't worthy. Also if anyone could recommend a good book on carbines it would be appreciated. Needless to say I have fallen in love with it in two day and thanks for any advice or info in advance.
