Re: Unknown Shure Cartridge
Yes it was. It was rolled out of flat beryllium shim stock around a tiny pin, in a jig. It was then put in a furnace to anneal and not just spring flat again. Then the overlap was glued.
US patent covering it is attached. But Shure lost the faith when CD's came out and scrapped all the gear for making them. So Shure were the first and last company to make stylus shanks out of thin-wall beryllium tube.
