Wanted: CMP Operating handle assembly
 

Hi All,
I am in need of a set of Operating handle assemblies for the crank on the stretcher racks in my CMP Ambulance 3G1 body. If anybody has a set for sale or trade I would be a very happy camper! I have part of the arm assembly that has been broken and welded together right where the pull pin that latches it in place is so would be next to impossible to re-thread again. Hoping to find a set of complete ones. The part number on the piece I have is 10457. The part number in the manual is DND/10431 if this helps anyone in identifying the part?
Thanks,Derk

Here’s more info on the part I need;
