Additional brass plaques are needed to match this one. It's located in a high school, and the font looks familiar to me, but I can't place it.

Knowing the age of the plaque would be helpful. If it dates from the early half of the 20th century, I doubt it is a typeface—it’s possible that it was hand lettered before being carved in low relief out of clay, then a mold was made of the carving to cast the finished plaque.

 

 

It may also be custom to the company that manufactured it—I’m not finding a match among modern digital typefaces.
