Jim, the red hub mold JFC chip is from Massachusetts. Guy named Carney. The street directory listed his occupation as "carnival worker". Late 40s I think. There's a thread of this in the archives... somewhere. I did some basic research on this chip at the Boston Public Library a few years ago. A couple of hours to research one chip! I don't know how others, like Gene Trimble, do it!

I believe chips from MA are hard to come by.

BTW, you have some great chips listed!
