WTB: Vickers Rear Leg Clamp - Pin and Tightening Handle

[WWImg]

All - Restoring an old Vickers MKIV tripod and need to replace the large pin that mounts the rear leg to the tripod socket and the tightening handle for the other side. The one in my tripod has severely stripped threads.

If you have one part or the other or both, I'm interested in purchasing. Photo taken of parts from another tripod.
