I deleted the attached pix that were duplicates of the 1 still visible.
From the 1 pix, nothing stands out as different then most (all?) Jet Stars I've seen, except perhaps the spray rail. What is it that you thinks makes it different?
I'm not 100% but that style of spray rail would suggest early 60s, but I don't know for sure if the Serial # includes year as the 1st 2 #s, which means a 1960.
Look thru the brochures posted at the top of the Starcraft forum
post some different pix
