Based on the great info in this thread http://www.savageshooters.com/showth...nufacture-Info My very nice 99 in 250-3000 Savage serial # 571xxx was manufactured in 1950. The LBC stamp is very different from any I have seen. It is not a light stamping and has no oval or even any part of an oval. It is not any letter or part of a letter either. I cannot attach a picture yet as this is my first post. The best description I can think of is a sideways keyhole with a small gap in the center of the round portion of the keyhole. This is a link to a picture I posted in another forum I am a member of.

I am just wondering if this is often seen, or an oddity. And is there any significance to this marking.
