I'm looking for a complete good working Burman CP gearbox for my W/NG. If anyone has one in good working order and is willing to part from it, let me know. Alternatively, I have one with code G108 B50 but it isn't working properly. If there's anyone out there who knows a company or a person who can overhaul these gearboxes or has an exchange program, I'm of course also interested.
