Nice haul of External Combustion Engines you scored there, Gil!
I've always wanted a nice Vacuum Rotor Engine, and have bid many a time, but usually come in as First Loser, so still don't have one in my collection. Odd that you seem to have acquired several SEPA or PMR burners without the engine models that those style burners correctly go with?!?!
Looks like you'll have some fun times ahead, getting to run that pride of engines!!!
