ORIGINAL: Nitro Kid
It's a Royal .40. I received it in a trade. I don't know much about it. Could sombody tell me how much it is worth, when it was made, how popular it is?
Looking at the prices of new .40 engines, your Royal is worth about $20.00 as pictured. If you have the drive washer, prop washer, prop nut and muffer,
You should be able to get $35.00 to $45.00 for it.
