Here's what I believe to be an early 1930 Model A Speedometer.
The speedo head floats easily when the gauge is lightly twisted.
I have not tested the odometer as I'm guessing you will be opening the case to clean and refurbish the mechanism.
Note the lead anti-tamper seal on the back. I haven't seen that before. Looks like it may be embossed with the FORD logo.
Sold as-is for parts.
Thanks for looking, hope you can use this part.
