I recently bought what was listed as a Royal 28. I received it and there is nothing on it that says Royal, the engne size is stamped on the bottom of the lug mounts. There is a spot on the side that looks like it might have had a plate glued on. Can anyone for sure identify this ? If it indead is a Royal (not doubting the seller just want to be sure) what fuel is best, and what type of run should I expect ? It is also said to be reworked by Dixon ( Tom ?). Thanks
