if you already have a 150 mph speedo, I would suggest you get it repaired and calibrated. call

it’s very tough to confirm a used one is functioning perfect. And no telling when that 50 year old one will go bad too. Could be days after you install it, or years after.
While you are getting yours repaired you can choose to re-face the black and white background with original silkscreen process. Or leave your as-is. Your choice.
