Bill, both you and Fred Von have helped point the right direction. I gather that the paint to use is probably Duplicolor Hunter Green engine paint. I watched Chellie Ramos' videos of these newly overhauled engines running, they appear to of that color. I left a comment on one video asking what paint and color she used, will see how she replies. I plan to mount it on one of my profiles, may be the late 1950's Berkeley Interceptor. Folks on the Ringmaster Brotherhood previously commented on how to mount left hand exhaust engines, I will place on the left side of the fuse so exhaust is pointing downward.
