Unka-Boo,
Nice toys. I think you are on the right track with the Steelcraft. But...it might also be early Buddy L. You might try checking out these sites:

Sorry...stilla newb here and not sure how to insert a link. I used to collect a few toys for my son when he was growing up...still do a few...but he doesn't seem to be much into them yet. So I've put them aside.
Hotwheels? We've got a few thousand. Yep...THOUSAND. Almost a complete set of the original 16 REDLINES, some still in packaging. Those are locked up in safety deposit. Other than that, they range from the later 70's to present. The newer ones don't excite me much anymore since they've gotten a bit carried away. Still a traditionalist I guess. Anyway, I hope those sites help out a little, if you know anyone who wants some Hotwheels, say so. I think we may just be getting ready to clear some attic space. Who knows maybe trade towards some other toys...AR or AK types
