Default Need info on old sheet metal brake

Someone gave me an old sheet metal brake but I'd like to find out more on who made it, how to adjust it, parts etc... And am hoping someone here might recognize it. It's about 24" wide or so. And the only markings I can find is 3 numbers followed by a dash, then one more number. (I forgot the numbers right now but it's like 206-3) Any info would be appreciated. Here's some pics, beer can for reference:

Well, first of all, it backwards. Turn it around and you'll be much happier using it.
That's what is known as a bar fold or folder. By the looks of it, it appears to be a Pexto brand. They don't make a real sharp bend. I spent way too many hours on one where I spent a huge amount of my working life. (20 years).

Mostly, I made guards with it. They were made from flattened, expanded metal that had an edging spot welded around the perimeter. The bar fold was used to bend the edging.

It excelled at that. slip a strip of sheet metal into it and fold all the way over. Then, set the piece of edging on top, insert the screen and smush it flat onto the edge of the screen.

I used that brake for other stuff too but, that was the main use.

There is a knob on the left front (once you turn it around), that locks the fence and a lever to move the fence in and out. The knob on the right is for fine adjustment of the fence There isn't a whole lot of adjustment, though.

I believe, they were made mostly for duct work. Capacity limit is about 22 gauge mild steel.

Well, the adjustment features look like the Pexto I used. The images of the Niagara that I found look different.

The last time I saw the one I used was 1994. So, I could be wrong.

Dag gone, I'm gettin' old!

Pexto, Niagara, Brown Boggs...not a lot of difference between them. Different models, too. Been a while since I had much to do with them either...

You've got a way to go. I remember stuff I was doing in ' 64 and '74...

Thanks guys, thatll help a lot. The knob on the front right is turning a little, but the front left one is frozen solid. I'm letting it soak right now.

Can I replace the big "finger" with smaller fingers to use it as a finger brake or is that not possible with something like this?

I've never seen smaller fingers for a unit like that. It's not really, a box and pan brake. As thin as the "big finger" is, I'm pretty sure it's hardened.

Yep, it's a bar folder all right, and that's all it's EVER gonna be. It's a limited use, specialized tinners / duct shop tool. I had an old Niagra in the shop for 6 or 7 years, used it ONCE, Trade and boot for a worn out B&P brake that has been much more useful.

I you don't have the need if it's "special use" nature, sell it off and buy a chinee box and pan brake. you will be much happier in the long run.

Yep, I'm afraid Red is right.

I gave you a bit of a bum steer about one of the adjustments in the first post.

I mentioned a small lever on the front. It's for moving the bed plate up and down, not the fence. In the first photo, those nuts at the slotted holes lock the adjustment. Loosen them and twisting the little lever on the other side and it doesn't move a whole lot, will raise or lower the bed to make the bend crisper or more radiused. But, like I said, it doesn't make a nice, really sharp bend like you can get from a real brake.
