It was made in 1924, according to "Ithaca Gun Company - From the Beginning". Value would be determined by GA, model, and condition.
First your Ithaca 20 gauge model 37 was made in 1969 and for the guy with the 371377097 your gun was made in 1974 I have model 37 serial 371473XXX and it was made in 1975.I have a Ithaca featherlight serial no 371377097 and it was built in the mid 60s. I found it on the Ithaca web site a few years ago, when there still was a web site. But have never found anywhere else to find out. I can't remember what part of the number said what 3 or 4 year range it was built, but I do remember that the numbers were in order from lower to higher in regards to older to newer.
look on the Side of the recevier there should be a Serial Number on the older Ithaca Model 37 the serial Number was stamped on the receiver by the magazine tune and Barrel . also if you take the barrel off on the bottom of the barrel you'll find the matching serial Number. then look up WWW.SURPLUSRIFLEFORUM.COM in their search engine type in ITHACA 37 DOM match your shotguns Serial number up with their chart .
You have an Ithaca Flues model made in 1915. Can not provide additional information without the stampings on the watertable, barrel flats and overall condition.

You can try looking for a replacement barrel for an Ithaca Model 37 shotgun at a gun store that specializes in vintage firearms or through online marketplaces such as GunBroker or Numrich Gun Parts. Make sure to provide the serial number and model details when searching for a specific barrel to ensure compatibility.

To whom it may concern, i bought a 20 gauge Ithaca Model 300 with a vented rib barrel when i was a senior in high school. i am 48 now. i have checked a few places looking for a slug barrel for this model shotgun. Most of the time i was told, i don't have one but i will sell you a extra smooth bore barrel and you can have it cut down, but i was looking for a rifled barrel. more than once I was told that Ithaca never made a slug barrel for that model gun, and since high school i have only seen one other person that had this same shotgun. i finally gave up on looking. hope you have better luck than i did.
The Ithaca Crass Model was named after Ithaca's Fredrick Crass who designed it. It was introduced in 1888. The serial number range for the Crass Model is approximately 7,000 to 50,000. There are nine different levels of quality (1, 1-1/2, 1P, 2, 3, 4, 5, 6, & 7) with appropriately escalating values.
