Thats pretty nice for sure, looks like an 80 inch UL flathead, the emblems on the tank definately indicate '52/'53. 10 grands not bad. The speedo probaly needs a new cable or its come loose from the backside of the speedometer or the sending unit on the transmission. Either way, a fairly simple fix. I have a '52 custom Panhead in my garage, original mill and trans, molded frame, cleaned up & tweeked, stock Linkert carb, some neat little tricks in the motor... Cool ride.
