You have a Flues model, built with pride in 1920.
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.
You have a Lewis or NIG model, built in 1903.
