Two possibilities, the Ultra Pro could be Eclatorq as they do a lot of SPC type things like the computer connection those wrenches feature. My best guess is KABO for the others as KABO makes a lot of Carlyle's stuff and they are very heavily into torque wrenches. Can't be sure about either one but these are my best guesses. If I had to pick one or the other I'd go with KABO.
