Buzz, I knew you were a fellow after my own heart! I had a Big Jim, too, and the camper set as a kid!! Also GI Joes and Hot Wheels (I'd love to track down a Thundershift 500 racing set at a cheap price for my nephews- I can't tell you what joy it brought me), and Matchbox cars! About McCrory's - at one point, our former Kresge's in Staten Island became a McCrory's for a few years, and then it closed down in the 80's.
Yep, my brother and I had Big Jims, then they came out w/Big Josh, Big Jake and another one that I *think* was Big Jack? One was black (Big Jack I think) and the others were white.
We did the GI Joe's too and do you, or anyone, remember the Best of the West collection? We had Johnny West, Jane West, Jesse West, a couple horses and another one that I can't remember the name of, but it was a black knight I think. There's this GREAT vintage toy store in Maryland called The Toy Exchange and it was there I found a mint Big Jim and Big Josh which are proudly on display at my house.
I kept my Matchbox cars up until a few years ago when I gave them to my nephews Jack and Sean, son of the aforementioned brother--they were pretty beat up from continual play--if I knew then what I know now about 'vintage/antique' toys.....
Anyway, I *did* keep my Batmobile and a Starsky & Hutch red Torino that I made myself, that is to say, I had a Ford car that sorta looked like the Torino so I painted it red and put the white stripe on it, before passing on the collection.
We also had Zayre's and Ames. Zayre's closed in the early 80's as I recall, then Ame's closed just a few years ago, maybe 2000?
