MUST have the same SN on the barrel about the 5 o'clock position.

IF NOT THEN have the HEADSPACE checked. As the barrel/receiver was specifically mated and headspace.

Any different SN barrel can be mated to your action, just need to locate one. They are getting scare(er).

Contact Diamond Gunsmithing, as the owner is retired [by the kings Ferry clowns] chief engineer of Ithaca Arms.

He can check out all M37's up to the Upper Sandusky take-over.

He did a 1954 16ga for me, and mated a 1948 barrel that he re-choked to SK and mated to my receiver and reblued per Ithaca specs. He also noted that the new barrel had bulged and wasn't accepting any responsibility for me shooting it. The original barrel was checked out as great.
the new blue on the two barrels and action REALLY make it look NICE!
