Why are they so rare/hard to find?
Blackhawk was not that interested in 3/8 drive, so it's pretty sparse.
Well ****, I won't pass it up anymore when I see it.
To add to and qualify Otg's reply, note that the extension - and the topic of its drive size sparsity, is from the early Quick Disconnect era! These tools are, in general, not as common as later tools to begin with. I don't think Blackhawk (est. 1919) added 3/8-inch drive ("S" for Small) to the Q.D. lineup until 1936, just before they launched Lock-On. So, they were - as Otg alluded to, clearly disinterested in making it.

But that's not the whole story. It should be mentioned, especially for non-Blackhawkers, that they ran into technical trouble. The 3/8-inch drive sockets were too small for Lock-On's release buttons. This put a crimp in their Lock-On plans, essentially forcing them to drop back to an approach to 3/8-inch drive similar to their approach to 1/4-inch drive. They continued making 3/8-inch drive right through the 40's and into the 50's, just not with the same brand-defining features as the 1/2-inch drive, with much less pizzazz, and apparently, much less demand.

Lastly, while they marketed Nuggets (7/16-inch drive) as innovatively economical (covering the larger half of a typical 3/8-drive service opening range and the smaller half of a typical 1/2-drive service opening range), it has been theorized that it allowed them just enough room for the release button, providing them a way to offer a good part of the classic 3/8-drive range with the Lock-on design.

(y), gives me enough info to study a catalog and familiarize myself what to look for.

I do see they didn't offer many tools in 3/8" drive in the 36 catalog and they all have an "s" after the part number. So the 3/8" tools in the 43 catalog with a 5 digit number are more common but appear to not be "Lock-on" and no "S" in the part number.

Right. If you look back, I don't think you'll see them in the earlier 30s cats. (I could be wrong, working off the top of my head here.) And while you will see them in the '43, '48, and '53, with handles (ratchets, extensions, etc) that resemble Lock-On in style, they don't have the patented attach and release socketry that gave Lock-On its name. Just conventional detent, which is functionally fine, by the way. It just futzed with their whole marketing (and tooling) scheme.

So these are all a little bit different from each other. Left to Right, an 814, a no tool # but in a 78XX style pat. pend. , a 7822S Pat Pend. A 7818S Made in U.S.A., and a 7816S but in the style of a 30XXX. socket.

That's a beautiful find. It even has the red recess stripes still in place. Be very careful with your selection of cleaner as those stripes can vanish if the cleaner is too harsh. Well done!
Thanks. It is in really good condition if anything I will just wipe it and put some paste wax just to prevent any moisture or rust.

Congrats, Don. Finding that 9004 release tool was one of the longest searches I've ever had. That's a nice Nuggies set ya have there off to the right. :)

Congrats to the find. I found one last year in similar condition. How are you going to clean it - blasting?
