Hi, thanks for the suggestions. The Parkin book has a couple of pictures but the clearest has the doors open and down covering the underframe. the diagram shown is of the body with no underframe detail. It talks about the underframe being a shortened version of the CCT one, but no decent picture or drwing of that either! Still looking for a clear view or diagram of the brake gear on the BR mark 1 Horsebox, or some idea of what to do with the etches in the kit! Hope someone out there can help...
Regards, Neal
