Hello Bob
They had a flawed
crank case which broke so were recalled by Fox if I remember the story correctly. It is early 50"s can't remember date but the 3 bolt back plate model replaces it in 1954 and some parts interchange with it.
I have one with a broken crank and meant to try finding a rough 3 bolt motor for its crank but it is nearly as rare now too!
Regards Gerald
PS here's a review of the latter 3 bolt 19:
http://sceptreflight.net/Model%20Engine%20Tests/Fox%2019.html also found this quote from Duke himself in his autobiography:
"Meanwhile, the .19 that we had been so proud of started coming back with the crankcase broken through the exhaust section. It seemed as though the casting was not only not strong enough to broach, it wasn’t strong enough to stand the stretch reversals from running for very long.
It was obvious that I was going to have to do something very quickly. We started a crash program to replace the crankcase with one of conventional design. As soon as the conventional crankcases started coming through, I sent out the word for a recall. Lordy, they sure did start coming back! For a while, it looked like somebody else was making them, because it seemed like we got back a whole lot more than we sold. Actually, I would imagine that there are less than forty or fifty of these split case .19’s left floating around."
