Stoker : here is pic of John Griffin letter that came in original ca. 1977 engine box. It was folded inside the numbered Andy Ross book, and thus the deterioration along the fold line. It was faded and I enhanced the type to make it more readable, the signature was too faded to enhance.
 I’ll try to get copy of other letter posted soon, its topic is the “Sun Motor” as original owner must have purchased that engine also.

Finally, a May/June 1978 Mother Earth News link to when they tried to run a Solar #1 with a fresnel lens. Anything “SOLAR” was a hot media topic in 1976-1979.
