WTB: or WTK: need M3 37mm AT gun worm gear elevation mechanism
 

I have two M3 37mm AT guns that are missing the worm gear mechanism for the elevation part of the gun. I have all the other parts and may even have a few spares.......but I need that worm gear housing that the rotating knob attaches to......anyone??? Know where one is? Prefer not to jury rig this and make a nice towable gun out of the carriage.......Have two guns need two worm gear boxes.
