SAR Red and brass train number plate.

I have a large brass train number plate. Measuring just over a half a meter across and weighing over 7kg's

Below is a wikipedia explanation about the train it was placed on.

"The South African Class 1E of 1925 is a South African electric locomotive from the South African Railways era.

Between 1925 and 1945 the South African Railways placed altogether one hundred and seventy-two Class 1E electric locomotives in service, spread over seven orders. They were the first mainline electric locomotives to be introduced in South Africa."
