Please note we have looked into the question of Cast Iron Brake Drums for Bentley II.A. and Bentley III, and find there are no designs. The existing Bentley II I/C Drums cannot be applied without special end plates being designed. Present design and instructions are for Alum Drums with Millenite Liners.
