Mismatched numbered WW2 Ithaca trench gun

[Tom Doniphon]

Regarding mismatched Model 37s, in 1960 Ithaca issued a notice about the danger of mismatched guns. It stated that around 1948 the company received several military surplus mismatched guns and there were problems with the barrels properly fitting the receiver. With some handy work they were able to make them fit and properly headspace. So one does need to be concerned about this issue. It's a good thing that Jimmyp08 had his gun checked out.
