This McCoy .35 C/L engine is like the one owned by my airplane flying
buddy, Jerry Flynn. He had it given to him, along with a lot of other great engines and kits, by an old guy who was getting out of the hobby.
This was back in the mid-1970s, so a lot of it was only 20 or so years old at the time.
I purchased two McCoy .35 Red Heads on eBay
in the summer of 2007, and one of them is proudly part of my personal nostalgia collection (above photo).
