this simple old device makes 4 different designs.. Through gears, dies and a crank handle. It can not only squeeze and deform a penny [coin] it puts a design like the example Mike shows. Some can be rather complicated and very well detailed..
We have been there already. We went thru all this 10 years ago. Look old topics. Depth of TK is too deep for this process. I showed my period giant rolling mill, even that machine can not make that depth.
There are less original rings than you think, much less...
