Hot Rods Speedometer question

can anyone tell the age of this speedometer? And what it was used in ? Thanks jimmy

 

No,but pretty cool with tach on it also.

 

No idea what car. But 500 rpm is 30 mph, that is fast

 

It is cool, no idea what it might have been used on, I suspect it wasn't an original equipment piece and I think it was an either speedo or tach, not combination unit.

 

Also bought this one today. I think it's new old stock. Hudson maybe?

 

Are there any maker's markings on face or the case? What is the exact diameter of the casing? (I'm guessing that it's smaller than the modern 3-3/8.") It's mechanical, right? Those pointers were popular in the 30's/40's.

 

No Markings anywhere

 

one gear, capable of 100+ mph and 1600rpms..........a train?

 

Over 5" diameter

 

The small speedo is 3 3/8"

 

The speedo/rpm gauge is out of a speedometer test bench. It is set up like that so you can calibrate a speedometer as well as a tachometer on the test bench. On American transmission driven speedo's 1000 cable rev's is 1 mile or 60 mph. I have one in my stash also.

 

that makes sense, thanks it was driving me crazy.

 

Thank you for the information . At least I know what it is now .

 

And the other one is Hudson, not sure of the year, early '50s.
