A Model 37 is a "pump", so a double barrel could not be a Model 37
easy Look on the barrel it should say if it a Model 37 , or Model 37 Featherweight, but the main Point is it should be on the barrel what Model it is

On my 1950s vintage Ithaca Model 37 16 gauge it is on the right side of the end of the receiver where the magazine tube and barrel go into the receiver, and also on the barrel adjacent to the number on the receiver. The numbers should be the same on both the barrel and receiver unless the barrel is not the original barrel, at least on mine they are.
Yes
On the bottom of the barrel where it meets the chamber.

The Model 37 is a pump gun, and the 51 is a semi-automatic. I doubt seriously that the barrels are interchangeable, since they are totally different models.
