sakorick,

You should also check out Jim's site about commercial carbines. Just a few years ago most aspects of the commercial carbines seemed a mystery, and most things I was told turned out to be wrong.
I bought two .22 carbines for my (then) young son, and became interested of their history but back then could find anything.

Jim did some unbelievable research to compile this info. (It's Phenomenal!)
He's also spent a small fortune buying commercial carbines, etc just to compile all the info. I get so caught up reading the interesting and sometimes colorful stories of the companies who made these I have spent an hour at a time hooked!

Jim is working with Ruth on WARBABY III. Does anyone know the status of WB III or any other updates?
