So then I assume the 1 is the cherry number.

Paul Jones did not use cherry's to cut molds.

I, too, talked to him in his last days in business, wanting a 25 cal mold. He told me that he won't make any more, that it was to hard on the tooling. 

The way Paul made his molds was with a lathe. He had several different radius nose forming tools that he used to cut the ogive and the 25 cal was very fragile and he would brake them. They are used like a long cutting edge, boring bar.

The reason it came up in my conversation with him, is that I design bullets with a particular ogive radius to fit the bullet diameter and the meplat diameter, with the ogive becoming tangent with the body and he said he wouldn't do a special forming tool for me but, would match it as well as he could, with his form tools, for molds that would be larger than 25 cal.

I contacted him a second time about a 28 cal mold but, by then, he had stopped making molds, all together. He told me that his son would start making molds in the future but, I don't think that ever, really came to be.
