Ran across this while looking for info on the new floor jack I acquired:
I did a google image search for Blackhawk SJ1 and ran across this:

Then I found this over at GJ, it's a Sears 727.12100 and it appears to be a Blackhawk (which unfortunately mine is not I assume), thought it would be good info to know (at least I'll now know a Sears Blackhawk when I see one now although I'd like a confirmation from Hiball that it is a Blackhawk):
