K7000 doesn't have any T03 transistors and that one does so it's not a K7000. I've heard there were some China knock off K7000's. It might be one of those but I doubt it. It's an odd ball for sure.
Looks like the seller got things mixed up. The second pic is a Wells Gardner K7000 while the first and third is a Sanwa PM1718 (schematics in this manual: http://www.crazykong.com/manuals/BoomerRangr.man.pdf)
