Take a look at the patent data (attached) Perry and make up your own name. I don't have a name for it. Surprisingly enough there are other style of handles with the same patent date and one I have has J. Read, Boston on the handle and he's the patent holder. Note sure if he made the pan or not but the handle on that pan does NOT follow the patent in that it is not rounded on the underside which I think was the main feature (for comfort) of his patent.
