Anyone have a MUNTZ?

Wow, what an ambitious project! Some of those sets are undoubtedly quite rare by now. I know of at least one set which is not on his list; a Sparton set which had the 23V5 chassis, which I played with as a kid in the early 60s (it took me 35 years to identify it!)

Evidently it was a 1955 model. which was not covered in the regular Sams Photofacts; they reprinted the schematic in set 309. I have never seen another one.
