I have two lavalier mics and I can't figure out the brand they are. I though they were Countryman B3- we have eight of them. I had sent these two to Countryman for repair, and they said they weren't Countryman. They have serial numbers on them, but no brand name. The serial number is on a red tape on the mic wire R78480. I have attached some photos that may help with this. (The second photo is with the screen cap off.) The mics work, but the connectors to the body pacs need some work. If anyone can help identify the brand name of this mic, it would be greatly appreciated.
