Need Part Number

Have an old Payne freight elevator that has a manual selector control in the car for the floor. It has carbon contacts that are worn out and I cannot find a replacement part for the contacts. Any ideas on where to find them? I found a part number for copper but not carbon. See attached picture. Thanks

ADAMS Elev , check in OTHERS OEMs next Payne Catalog V18 page 402

Thanks, but that's the copper contacts that I found but I need carbon contacts.
