I recall Harold donating his Pobjoy to EAA at Oshkosh ‘80, because I was with Gene Chase when he accepted it. It was the only Pobjoy I’d ever seen and it reminded me of the comic strip character on the cover of Trade-A-Plane in the mid-70’s that used to refer to them jokingly. I don’t know whatever became of Harold’s engine. There were some shenanigans pulled back in those days and the culprits are now either dead or still not talking.
