i appreciate every thing posted about claw mounts. i am new to german mauser rifles and the reason i started this thread is because i am looking at an original oberdorf mauser model b in 30-06. it is in very good shape and i mentioned it in another post.every serial number matches and is said to be all original except it does have the claw mounts dovetailed into the front ring.there are no rings for it.and i am wondering if it would be safe to shoot.headspace can be checked but since the claw mount may or may not be a factory installation i know of no way to determine if the rifle is safe to shoot or not.i have no photos at this time.the previous owner bought it but never fired it.it has good open sights.the bore is near perfect and everything looks good to go.thanks john
