We need better pictures.
I seem to remember that Craftsman offered a similar ratchet with the thumbwheel for a VERY short time, but I don't know if it was that model.
The other thing it might be is - Craftsman offered metal add-on thumbwheel disks for a while that slipped over the anvil of the ratchet (later they were blue plastic). It may be one of those.
Ha Ha - no, I didn't even look at that one. I was focused on the ratchet in front. 
IIRC I've seen some Asian knockoffs with that selector.
It's just a Japanese ratchet where they copied the Craftsman selector. I've bought one or two over the years. I've also seen other Japanese no-name ratchets that were trying to copy other Craftsman designs.
I have had several Japanese made ratchets exactly like that over the years.
