470 was missing the zero on its front number plate, so Bob set about to fabricate a new one. Looking back at old photos, things changed over the years. We believe only the number 4 is original. The 7 was changed and is stamped MCRR. The lower 1/4 is a brass repair or possible alteration of a bronze 2. The 4 is all bronze and marked with a 7. It was riveted in place with bronze rivets. The 7 had screws.

The new zero was machined from brass. With the mixture of brass and bronze, they didn't look right polished up together. Bob used an easily removable gold wax based product to make them look the same. At a later date, we can use the brass zero as a pattern to cast a bronze one.
