Hello, Pretty new to the forum,but lots of knowledgeable here. I was wondering if anyone knew the Serial number range of WWII issued Ithaca Model 37 Trench guns? I've been offered one that is serial numbered S23xxx Ithink the gun was made in 1940,but the 'S' is throwing me off a bit. Also the shotgun is US marked. I have read that WWII Ithaca shotguns were not US marked. If this is the case then was Ithaca Shotguns were US marked? My knowledge of Ithaca's is limited so any help is greatly appreciated.

The Ithaca 37 is a pump-action shotgun made in large numbers for the civilian, military, and police markets. It utilizes a novel combination ejection/loading port on the bottom of the gun which leaves the sides closed to the elements.

The WWII Ithaca trench guns fall into the 58,000 to 62,000 serial range. They have a blue finish, and they do NOT have an S prefix to the serial number. The Vietnam Ithaca riot guns have an S prefix to the serial number and they are parkerized. They are US marked. Zaryadnoe ustrojstvo iz bp kompjyutera na mikrosheme sg 6105 2016. There are a very few (only about 200) Vietnam Ithaca trench guns with an S prefix. The rest of the Vietnam trench guns are in the high 900,000 range. These are US marked.

In addition to the above, there were a bunch of Ithaca riot guns that were sent over to Vietnam for use by the Vietnamese, not US forces. These guns are usually riot configuration, and many, if not most, have what appears to be a hand stamped S prefix serial number on the barrel and on the forward face of the receiver as well as a second non S prefix serial number on the side of the receiver. These may or may not be US marked. Does the shotgun in questions have one S prefix serial number or the hand marked S prefix number and the second serial number on the side of the reciever? And what kind of finish does it have. AFAIK, the WWII Ithaca shipping records have not been published.

I do have a copy of them if anyone wants me to run a serial number check on a gun. The WWII Ithaca trench guns fall into the 58,000 to 62,000 serial range.
