Nice ... they are classics to be sure!
Is your's numbered?
Both classics and survivors ! Interesting that little red & green Stirling engine is still made today in USA 2020.
The ratty condition Solar #1 I have is not numbered , nor was the Ross book that came with it ; so it’s probably a 1980’s version. But the likely late 1977 version is numbered. The original box label, the engine, and the book for the 1977 engine were all numbered the same. Two separate letters were included in the accompanying numbered book by the CEO of Solar , and the other by the Andy Ross 1977 book editor.
