On their website they mention Seagrave:

“TWH Collectibles has produced construction and mining replicas for industry leading companies such as Bucyrus, Letourneau, Manitowoc, and P&H. But through relationships with Oshkosh Corporation, Pierce Manufacturing, Jerr-Dan, and Seagrave, TWH has expanded its line considerably. We believe that a redesigned distribution system will better serve the passionate collectors of these fine machine replicas,” says Nicholas Neumann, V.P. of Sales and Marketing.
