In 2007 a limited series of 25 bronze castings, made with molds pulled from Burt Munro's handmade rods and pistons were cast, intended as keepsakes for friends of Munro and special fans.

Bronze castings of his home made pistons and connecting rods; which were produced in a local foundry in Invercargill N.Z. These are both marked #3 of 25 sets made.
