I don't really know much about Upavon, but I think that they used to have a few Rapides there for parachuting. I gather at some point (Date anyone..?) they had a sale. A friends father bought some Rapides/Dominies, spares and a load of Queens. I'm not sure how many of the Rapides have survived, but I bought the engines some years ago.
Any photos or memories of the auction appreciated. I'm guessing mid to late 1960's.... Over to you guys...
