The original had a pin that you apply pressure with your hand to rotate the shaft (with a bit inserted in the end) to loosen the fastener while you rattle the tool and fastener.
I have 2 of those. One with a 3/8" square anvil, and one with a 1/2" square. And the adapter to use the screwdriver bits that come with them. They have definitely come in handy.Oh so that's what the hex is for. I'm new to air hammers, I think I used mine for the first time last year.
I got my first motorcycle in the '70s. Japanese bikes back then had soft Phillips (or JIS) cross head screws that stripped easily. One of my first tool purchases was an impact wrench. Not an air or electric one, a hammer powered one.
The chrome outer part slides back and forth on the shaft. There's a spring inside and a ramp. Hit it hard enough to compress the spring and hit the ramp, and it turns the bit while delivering the impact to it. It works pretty well.
I have one of these (Matco ID67 it’s stamped). Works great. Glorified yankee push drill. I bought it 1979-80 time frame off the tool truck when I worked at a Honda motorcycle shop.Oh so that's what the hex is for. I'm new to air hammers, I think I used mine for the first time last year.

That is the very first tool I ever owned. Exactly the same. Still have it in my box.Oh so that's what the hex is for. I'm new to air hammers, I think I used mine for the first time last year.

That’s like mine. From memory, the bit inserts are a little larger than common 1/4” impact bits. Don’t remember the size or where I got them.I've seen people use this sort of tool online, it has a handle so you can apply twisting pressure to the screw at the same time. It looks like it works great and I'd like to have one, except that I don't have an impact hammer.
It bangs on it, while you turn the bit with a wrench
We always called them Shake and Breaks, but that is just one brand’s (Wivco) name for them. You can find them from 30-40 brands.
First one I ever had in my toolbox, came out of our grind shop in 1942...We used to make a lot of our own hardware, rivets and tools due to it being wartime and supply chain issues.
First thing I bought too had a flea market at the local Stockyard I think everybody that had a dirt bike in the 70s or early 80s had one of those. I think it was collusion between the Japanese bike makers and the Chinese tool makers.
