RE: McCoy engines
Hank:
McCoy is one of the seemingly very few engines that MECoA didn't buy.
Dick McCoy, who died just a year or two ago, started the company before WW II, after the war the company became "Duromatic," this name was stamped on the end of the right engine lug of the 49 and 60 engines for a while.
When Testor's bought them out they continued making the Red Head 60 engines to the same standard as the older ones, I bought my last new one in that 60-61 period. The 19 and 29 racing Red Heads had been discontinued a few years before, along with the 49 Red Head.
The 19 and 49 were discontinued when the c/l speed classes were changed, class A went from 19 down to 15 maximum size, and the old class C with a 49 size limit was dropped, combining the old class C and D into one class C with a 0.65 limit.
The racing 29 Red Head was dropped in the early to middle 50s when the K&B Green Head 29 engine was beating all the Doolings and McCoys. McCoy tried to keep up by going to the slug piston, but it wasn't enough. The Dooling brothers hung on for a while longer (bought my last new Dooling in 1960 - $24.95 - makes me sick to think I sold it) but eventually they quit too. Their 61 hadn't been competitive for a good while before that.
Enough for now, far more than just an answer to MECo and McCoy.
