It seems to me the intention was to create something that would function as an adjustable crowsfoot, but be used without modular extensions or handle/ratchet.
Maybe. I gave it some thought, if only to dispel the even more depressing notion that someone did it for kicks, and your theory is more than I could come up with. I was trying to picture it alleviating an obstruction, i.e., a fastener in a narrow opening that was blocked in front and below, but, it wouldn't be able to turn on that axis. Something in a hole, like old fixed crowsfoot wrenches, or a crowsfoot on an extension makes sense, but again, you couldn't get much leverage on the turning. I will tell you that the right angle is spot on 90*. I had it on an angle finder. So whoever did it and for whatever reason, they were determined to do it "right." But there are a hundred other crappy adjustables I would've done that to ahead of a beautiful vintage double-ender BAHCO.
Which is a good segue to respond to your broader points.
I can sympathize with Blake's position above,
partly. My position has been pretty well known even before we had this thread, and I've been pretty consistent on the thread with my examples. I am fascinated by modified tools, in general, due to role that "Necessity is the Mother of Invention" and oneupsmanship played on drawing boards and small workshops in the history of hand tool evolution in this country. As Outlaw alluded to, mods are not so far removed from the commercial innovation. And I have a small collection of them. But I don't like or approve of them all, all the time.
Some are necessary. Some are unnecessary, usually because there
is a tool built for the job, but the guy who made one, ruining two or more other tools in the process, either didn't know it, or knew it, didn't have one, and couldn't wait to acquire one. And some are unnecessary because they're just ridiculous. (Many multi-tools in this category, a concept that can and often does get taken too far.)
When those are modern tools, I don't mind so much. When they're antiques or vintage, it is a shame in my book.
And then there's execution. Some are done well. Some are ugly.
When a chopped tool is vintage
and unnecessary
and ugly, well, it's three strikes against "Bubba", a term you will see Don and I and a few others use, derived from the Military Vehicle resto world, used to describe a mechanic who took the hasty, crude, and stupid approach to something, usually involving a torch, a hacksaw, and a welder.
