Speedometer identification

[unclemiltie]

I have a 416355 and a
417295 speedometer heads. The boxes say studebaker truck. Does anyone know what they fit? They are in SW Stewart Warner boxes

Those must be SW Part Numbers, is there a Studebaker Number on them 5XXXXX or 6XXXXX?

We could I.D. them with a Pic.

My guess is M series or 2R series (there were two different types used in 2Rs). The 3R series had one with S-W number 420xxx.
