This is an old Keller boat speedometer. The plastic lens covering the face of the speedometer has yellowed a lot. I'm not sure if the lens was originally flat or bubbled out convex like but it may have sat in the sun too long at one point and warped the lens.
It is painted grey in an industrial krinkle style paint. I think it goes up to 52mph but look over my photos real close and decide that for yourself.The chrome is in decent condition (not perfect but not real bad). I have no way to test this. Maybe it works, maybe not. This item is in the category "eBay Motors\Parts & Accessories\Boat Parts\Interior, Cabin & Galley". The seller is "thejunkpunk" and is located in this country: US.
