I need some good clear pics of a M1 carbine bolt to compare to the one I just received in the mail. Hope someone has some,Thanks for helping. Vonn
 
There is a difference between an M1 bolt and an M2 bolt. I have seen many M1 Carbines with M2 bolts. Is this the question you have?
 
There are basically three types of USGI M1 carbine bolts:

Type 1 - Was the original production design. It had a flat top surface with the extractor area cut all the way through, leaving the bolt lug area weak. These early bolts were prone to fracturing which caused the right lug to break off. Only early Inlands and Winchesters used these.

Type 2 - Introduced in mid 1942 to replace the Type 1 bolts. this was a flat topped bolt with a reinforced web of metal under the extractor which solved the breakage problem experienced with the earlier bolt design. All USGI carbine prime contractors used this bolt at one point.

Type 3 - In late 1943, Inland experimented with the round bolt. The design proved successful and was adopted in March 1944. Erroneously called the "M2 Bolt", the new design eliminated a number of machining steps and created a better bearing surface with the receiver for a smoother operation.

"U.S. M1 Carbines - Wartime Production" by Craig Riesch is an excellent source for carbine information.
 
Have a Saginaw that my brother had taken the bolt out of and when he died my sisters probably tossed it and a couple of others out when they were cleaning out all of his things(huge job). I have the proper year Saginaw bolt but didn't have any to compare it to so I was looking for pics to see how much wear,etc the one I got might have .I think I have found what I needed and I know how to check the head space etc. Will post pics when I get it all clean up. Thanks for the replies.
 
The M1 carbine is pretty much over engineered for the ammo it shoots. Never heard of a bolt wearing on one. Breaking yes, but not wearing. The only real weak link on a carbine is the extractor.
