An example of the one that probably started it all, this is the only indenter for multiple sized fittings. It has interchangeable jaws that were easy to swap out. If you only wanted one tool for the job, this was it. Measuring 17 inches long, it was anything but pocket-sized though, and the smaller indenters were developed. It still appeared in the catalog as late as 1962. I have examples from both Galva and Moline. This one is from Wayne Craig's estate.
