ID These Gauges

I don't remember where or how I got these, but I think they date from the '60s. They were in a box of parts in a cabinet. 3 3/8" diameter.
No name on the face. On the back it looks like S.W. and some numbers. Are they made by Stewart-Warner (S.W.)? I'm thinking of using them in my latest project.

 

I'd say 62-64 Studebaker GT...but should have a 160 speedo....

 

my first thought was stewart warner too...

 

They look like they're off of a motorcycle to me.

You guys are good. Yes, I bought a '62 Stud Hawk cheap from a friend, around 1968 - 69, for the 4 sp ******. It would bolt up to Chevy engine. I must have taken the gauges out at the same time. Sad to say the rest went to the s**** yard. Thinking about it, the car was fairly new, 6-7 yrs. Got to look around, maybe I have the other gauges. Thanks.

 

62? stud? really? i really thought they were for a delorean haha
