This is hand-cut lettering where the original metal Spacerite Modified Roman letters were used to layout the inscription. The MLC has created a font to match this type of lettering, but due to the hand-cut nature, there are often still some differences. In this case the serifs seem to be somewhat longer than the MLC version, and would need to be manually modified to match.

The crossbar on ‘A’ also seems to have been manually dropped down from the original metal letters. However, the MLC version of the font has an alternate character available to match this letter, when using software that supports OpenType alternates.
