I see no part number, but you may be right about it being an OEM part.
"Leviton" is embossed on the plastic/Bakelite back, but "UND LAB INC"
is engraved on the metal, and that appears to be an actual company
name.

It is a company name. Underwriters Laboratories Inc. They don't make
anything, they test products to assure they meet certain specifications.

You may get lucky and find it at an appliance repair shop. Especially
one that has been in business for a long time and is an authorized GE
shop..
