The 56000 serial number range denotes a 1942 built gun (according to Snyder's book 1942 = SN 50901 to 63000). The serial number appears to be a bit early for a 'real' WWII Ithaca M37 Trench Gun. According to Canfield's book the first quantity shipment of M37 Trench Guns was 19 June 1942 of 100 guns SN range from 57800 to 57995 indicated by the invoice. If it is one of the few (only 1422 WWII M37 trenchies were ever built) 'real' WWII Ithaca Model 37 Trench Guns its worth well into five figures. The M37 and the Remington Model 10 Trench Gun are reportedly the pinnacle of a collectors collection. The guy I got my 1969 vintage M37 trenchie from was selling it (and a lot of other awesome shotguns) to fund the one WWII M37 Trench Gun he had found. Never told me what it cost him, but it looked like he was selling about $12,000 worth of trenchie/riot goodness.
So, there is a slight chance you have one of only a handful of 'real' WWII Ithaca M37 Trench Guns, but according to the little bits of info I've got, it sounds like it's a bit too early. Be that as it may, the 1422 guns all had receivers devoid of the classic Ithaca hunting scene rollmarked on the sides of the receiver and those guns had a blue finish (not Parkerized). The buttstock was smooth and the forend was of the 'rigtail' variety.
Now I've got to disagree with cplnorton here a bit. Before I bought my '69 trenchie I was working on building up a clone. As it is now it is going together on a 1940 vintage M37. The barrel has been cut to the proper 20-inches and crowned and neither my reproduction East Taylor bayonet mount/heat shield nor my real set up fit loosely on the cut-down 1940 vintage barrel, rather both are extremely tight.
Do you have any pics of your shotgun you can share? What is the choke denoted on the barrel? Before you go shimming or soldering anything it might be good to look into it a bit more.
...and because I like to post pics... my 1940 vintage M37 Trench Gun project.

Location (State): California (CA) Member For: 16 Years 6 Months. Ask Seller a Question. Make: Ithaca Model: 37 Serial Number: 333070. Our Assessment: This is an Ithaca model 37 in a great configuration for hunting or trap, with its 30' barrel and full choke it should be able to put shot on target even at longer distances. Ithica 37 serial number question I just picked up a 16ga 37, the serial number dates it to 1957 according to what I could find on the net, 664xxx. My question is that the serial number on the barrel matches but has a -2 after it. May 22, 2011  'Ithaca did produce Model 37’s between 1944 and 1945, but they were not kept track of as far as the serial numbers. Your Model 37 would have been manufactured between 1944 and 1945.' That's direct from the factory.
