Well guys. The brass speedometer isn't brass. A little soap and water cleaned the green patina off. Brasso, great for brass right, took the rest of the green and brass off. HA HA. Must have been Arkansas brass out of a spray can. It sure did have a shine. What is left is a red primer with traces of the original hammered silver paint. Thanks for all the comments. I thought I might have found a rareity. Just goes to show what has been done to these beloved little scooters over their lifetime. Its always a learning experience.
