Unless you happen to find someone who is doing a "numbers-correct" restoration, that spray-oiler 235 is going to be a hard sell for more than scrap iron price. Rebuilding parts are scarce and e$$$pensive, and a later model 235 with full pressure oiling is virtually a drop-in fit for most applications. If your engine has the short pushrod cover that doesn't overlap the cylinder head, the head alone is probably worth much more than the rest of the engine.
