Thank you, very much appreciated, sir. Any thoughts on Spec number? It has solid spoked flywheels, no pulley groves so assume it was generator spec'd.

Spec numbers were assigned to every change in the CS line, be it an improvement or a special order. Thus they could ship correct repair parts. They are often confused for dates but they are not. To my knowledge there is no comprehensive list of spec numbers and the changes. A few if them were known by David Edgington and listed in his book.

Right on, Thank you for the information. I got the old girl up and running. Cylinder two seems to have a stuck ring perhaps. It will run but smokes a bit when I release the change over valve. exhaust isn't as warm, as the other. Not sure if just running it will loosen it up or not.  ???
