This is a tough one to find in good shape and yours looks good! 140, 68, 80, 44 and 152 are a couple of other non subscription volumes that are just as if not tougher.
Actually there are 4 versions, USA, USA-1, USA-2 and USA-3. I dont know what the difference is between USA and USA-1, but the USA's Ive found, for the most part, tend to be coming out of Canada for what ever reason.
Ive yet to see either karate kid or side pocket with 5 screws, however I can confirm RC Pro Am exist, I have one with security screws, prolly left over shell. Refurb carts usually have no back label, i think.
I still have an old newsprint game menu advertisement that I kept. I should post a pic, its a trip. Got a lot of good stuff from that place and past up alot of good stuff also.
