Looks homemade to me.
Get some proper rod and a brass wrench you can solder, and solder it.
Bronze rod from the auto parts is not as easy to pull off when the parts are delicate. Big heavy parts the bronze is just right. You heat the whole project just about cherry red until the brass flows. But it flows really near the melting point of yellow metal.
So when the solder is flowing on brass work, you better be real real careful,
or that yellow wrench will be a puddle, and so will the hammer head.
You are taking the work to the razors edge of melting.
It may be brazed with brass, but I would be suspecting ---------silver--------- if I were you.
Silver solder is just about tits. There is absolutely nothing unlovely about silver. It solders almost anything to anything, with little danger to the work, and when everything is j-u-s-t right, ....
it flows like sweet honey and sets like a hard rock. Silver is fantastic, in a word.
Well.................. the cost of a date with the girl may have you looking around for other alternatives pretty quick. It costs a................... fortune.
Yeah yeah sure the first time you use it you are willing to spend anything, but then the second time comes around and the third, and soon your jewelry quality solder is flat gone. Its going to cost you a case or two of beer to replace it. A genuine bite to the ass.
Now what?
In between silver and bronze solder, there is tubing silver solder, which is really for plumbers and air conditioning guys, and others who work with higher pressure tubing. Its got some silver (up to 20% the most expensive) and some bronze, and other metals in a mix.
It works really really good, if its the old fashioned stuff with a tiny bit of cadmium in it. (tiny tiny bit, but its important)
Cadmium is dangerous. If you screw with it, it'll kill you, soon.
But if you let it kill you, you are too dumb to be allowed tools in the first place.
Like anything else that actually works, its dangerous and you take proper actions to keep safe. Safety first. Suit up when called for!
If you make sure you are safe, its really remarkable solder. Oh geeze it flows near as good as pure silver, and sticks any two kinds of metal together you would want. And costs about 1/3 as much as pure silver.
The "safety" refrigeration solder, available anywhere, (no cadmium) works too........ up to a point,
but it will never be as versatile. You'll see if you ever compare the two.
If you pay attention to your peas and Q's the old "dangerous stuff" is a dream on skates.
Almost like real silver.
You have to dig though the dusty places to get it though.
If I was a betting man, I would bet this tool is soldered together with refrigeration solder that has a trace of cadmium in it. Somebody do a chemical analysis.

PS Be sure to click and blow up the picture. It sure looks silvery to me.
