The Automobile Gallery of Green Bay, Wis. (www.theautomobilegallery.org) has a Dort Speedster with Lycoming Motor No. 30630. The plate on the engine looks like there could be an X or K prefix and a B suffix ahead of and behind the numbers. We are trying to identify this car as to year, model, VIN, etc. so that it can be titled and registered. So far, the state has refused to accept registration documents for the car.
