i think most of the crocodiles that you see around now came from pounds yard in portsmouth back in the eighties, if you want a crocodile then it's still possible to find them but only if you contact a museum and make an offer. with things being the way they are at the moment it would be a good time for a museum to release an assett or two to raise funds so you might be in with a chance as to value i would expect to pay £30k+ for a fairly complete but unrestored vehicle. failing that you could try the cadmans or nigel montgomery as they have probably got 15 between them. there is one other avenue open which is to recover a range wreck but i don't know how feasible that is with all the health and safety issues that seem to be in place at the moment but anything's possible if you keep at it.
as it happens a friend of mine sold his mk7 churchill last month to another collector so you could have a shot at that although it's too late now but it does go to show that they do still come up now and again. as for my churchill i only paid £3.5k for it 2 years ago which basically equates to it's scrap value which is understandable if you've ever seen it :blush: but it's a start.
good luck with hunt

ps. the churchill is the daddy
