I had a chance to buy an S29 and it's later model, the S-39 about 30 years ago. They were scarce, even at that time.
Production was curbed because of the war. The S39 seemed to be built for the US government and others as a moral receiver.
The schematic on the S-29 is available on the website, Nostalgia air.
Dave, trying hard to remember.
