I believe this cluster is custom built.  Thinking for a 50's Chevrolet Truck
I believe the gauges are from a 1950's GMC Trucks.
I am often wrong, so please verify.

Good Cosmetic Condition. 
Speedometer & Odometer both tested functional using an electric drill. 
Oil and Amp gauges also tested functional.
Not including the length of the three mounting tabs...
Approximate dimensions are 12 1/2" x 6 1/2".

I am happy to combine shipping.
Thanks for looking and Good Luck, Pete
