These are in great condition. Outside is weathered but not thin, these are solid. inside and glass with Robert Bosch name as new. All latches goed. I have more photos.
Spins like a top, nice inside, fits a 60mm hole. Black face plate is not nice after some fool glued a homemade piece of paper on the original faceand uped the top speed with a pen to 200kph. Maybe to impress his girlfriend !! So maybe you have a nice face plate and a bad speedo. Then this is your chance to get that speedo fixed...
