Battery Holdens-Chev MCP 216 engine

[motto]

Lionel, I think that your battery rack should be able to be recovered as it has not so much been butchered as added to. So long as the frame is in reasonable condition the only part that needs replacement is the folded sheet metal which is 16 gauge x 4 inches wide, folded up at each end and riveted to the frame.
The most difficult part is the fact that there are rivets involved both in its construction and attachment to the chassis.
I threw my rack away 30 odd years ago as I considered it a silly place to put a battery and I came up with a better one to put on the outside of the chassis.
