I will guess 462. I have a list somewhere of all the ones I have, and a few that I don't from Mac's book. I forget what the count was. I don't have any puter cars or 1:24 ones, and have no idea what they are, as far as casting numbers.
I have a list of what I have, plus what I'm missing from Mac's book. I am missing the Batman kits, Pewter, 1:24, and a few other newer things. Maybe we could all QA it and send me changes/additions as you find themand we could compile a good listing. I have to double check to see if I have added the most recent castings, like the Toronado, '71 Challenger, and Golden Hawk. If I have a chance, I'll work on it tonight. It would be better to get something like this from Johnny Lightning, though, since my list is incomplete.
I have a table in my database just for casting numbers. it currently resides at 382 unique castings. No 1:18 or pewter and I've still yet to get all the series online like you have Wyatt. Missing I know are the HOW and Military Muscle but there are more.
If you'd share you lists I could add it to my table and spit out a webpage just for castings. I've been meaning to do just that for about a year now but there are only 24hrs in a day. Dang !
If Pm - Rc/Ertlwould continue on with the Streetfreak/Rebel Rod line we could find out. We need every casting done with a meatball number and Blown motor sticking out of the hood I'd guess, 200 castings
