Does anybody know the name of the company that produces the rubber gaskets for the microphones, the seals that hold the elements in place. I've got and old shure 520 that needs one, and my latest piece the W80 needs one also. I had this info in my old computer.....but it's dead now and unfortunately I could not retrieve the info on the hard drive. I tried looking on line, but I'm probably not using the right keyword? any help would be great
