Hmm.. yeah, looks like that radiator is out of a Ford Falcon or similar... it has Ford's classically scalloped top tank. I'll bet it didn't cool very well, though, give the huge gaps on either side!
As to value.. well.. it does have a factory radio setup, so it's at least worth $500. It has a factory cigar lighter, too, and cleaned up that would pull around $100. Despite its surface-rusty appearance, it seems to be a largely cancer and dent-free bucket, so it may do as a potential body-swap for a substantially rusted-out car. Further, it has a rather interesting Rootes-related (or is that Volkswagen??) emblem in the centre of the fascia (dash). It also has a *very* unusual homemade single Zenith-Stromberg carburettor setup in the boot... never saw one of those before... and an early down-draught manifold in there as well, atop the pile in the boot. I'd give it a value of around $1,700.
