Little Giant Brake and Notching Tool

[ihrescue]

Hi folks: I am a small scale, DIY, garage metal shaper. I have a question. Years ago I obtained a small brake and notching tool called the Little Giant 4 in 1. The manufacturer was William J. Tatu, Inc Williamsville, NY. The second accompanying tool provides notches, punches holes and crimps. Works pretty well. The main brake is about 30" long. Here is a web site showing one at an auction. I also attach a couple of photos of the two tools - a little rough after sitting in my shed. I wanted to see if anyone can offer more info on these tools, especially documentation, users manual etc. What I am real interested in knowing is what is the maximum thickness of sheet metal that can be used with this small, bench use tool. All comments and suggestions are appreciated. If nothing else I thought you all would enjoy seeing a tool that appears to no longer be available.

I own the second tool, bought it in the 70's to do minor sheet metal work building race cars in the garage. Here's the sheet that came with it and this is all the "documentation" that did!
