American 20th Century Side by Sides

[Researcher]

There were barely 2000 Philadelphia Arms Co. FOX doubles. Baltimore Arms Co. guns have serial numbers from about 1000 to just over 7000. The serial numbers show just south of 20000 Tobins.

Some others to consider would be Forehand & Wadsworth --

These Hopkins & Allen sideplated guns appear to have some of the features of the later Iver Johnson doubles --

Savage? Or is that considered one that you own already (ie savage/fox...etc)

Savage Arms Corp. actually very briefly offered a double, the Model 320 --

Model 320, January 2, 1937.jpeg

Introduced in their January 2, 1937, catalog along with their Model 220 hammerless single barrel and Model 420/430 over/under. The Model 320 was a trigger-plate locks style gun. Apparently Savage decided a better answer for a lower priced double was to take the internals of their J. Stevens Arms Co. No. 530. put them in a bit nicer profiled and black gun metal finished frame with a bit nicer stock and besmirch the Fox name by calling it the Fox Model B --
