It's funny that I just now read this post, because I just found a batch yesterday. They were at a antique mall here in town and even had the boxes with them. everything in Japanese, very cool cars as well. I would say from the 70's?
I looked at several, but at $20 each, I left them there. I thought I would check back from time to time to see if they run a sale on that booth. If you want me to go by and make a list of what they had ( 10 to 12 cars?) just email me and I will be happy to make the stop.
I mean, if I just HAVE to stop and look at toy cars, I guess I could!
