My book shows '64. Savage is correct. The only difference on the 88s and 100s is the stock before or after the Winchester cheapening in '64.
If your 100 has cut checkering, that is a pre'64 rifle although the SN puts it in '64, if it has a pressed (cheap) stock it is a 64. There were possibly cut stocks available into the '64 run so the assembly line guys may have found one and just placed it on a '64, but who cares?
Bottom line, it is the same rifle (mechanically) either way. It's a deer killer not a Winchester Collectable ANYWAY.
If I hadn't sold my 88 and 100 collection, I'd buy yours just to put and end to this nonsense.
