This is a new old stock factory Coats 8183641 helper arm hold down foot that fits various APX series and rim clamp tire changers equipped with a bead pressing helper arm. This is not aftermarket, it came directly from Hennessy in the early 2000's and has been sitting on a shelf in my garage since then. I saw another one listed online for $263 that looks slightly different with the same part number so either Coats changed it over the years or that one is aftermarket. Please check out the other factory Coats and Ammco service parts and accessories I have listed.
