I have quite a number of JF bodies mostly purchased at my LHS.This way I can examine bodies before purchase. Like some here,I have differing opinions on different bodies . I think it totally depends on who did the master .Some are outstanding (the Hornets,Courier SD etc.), some are very usable with a little work(55-57 Suburban), and a few are way too thick and only suitable for shelf models or curbsides. One or two are too much work to make anything realistic out of.
Considering his reasonable pricing and the overall desirability of the subjects, I would recommend almost all of his stuff. I also know from friends who have purchased directly from Jimmy that he is fast ,honest and easy to deal with.
That said it's always good to see what you're buying first hand, if you can, like almost anything in life !
