Dang it, another one I'll have to watch for! Well actually, I've already got three in 1/2 drive - just that none of them are Herbrand:
A Vi-Chrome, a Bon-E-Con, and just recently, a very nice chromed Bonney.
Only Herbrands I've seen/have are either the older ones with a slide button (or older yet with a lever switch), or some much newer ones with plain block lettering, no country-of-origin, and a really cheap import feel.
Now the big question is, who actually made these style ratchets? Did Herbrand make the Bonney branded ones, or vice-versa? I'd say it's a fairly safe (and obvious) bet that these date from the Kelsey-Hayes/Triangle 1960's eras when Bonney, Utica, and Herbrand were falling under one ownership roof, but who actually made them?
That's a nice find!
