HA! Bill, I do not have one right now. All I have are NOS in the box units. Since the car has just the right amount of vintage patina on it, I would look at some slightly used tachs on ebay. I have used Gary the Tach Man for restoration along with Williamson's Tach Repair. Both produced excellent results.
Here is what I found... they're on ebay all day long. Chrome cups are easily found too.
