Fabrication of N&W Number Boards

[nw-mailing-list at nwhs.org]

With y'all'z indulgence, I'd like to revisit a question I raised on the List several years ago with inspecific results.  Hopefully this time around, there may be "new blood" in the List gene pool, or perhaps someone will have run across a record...

What was N&W's practice on the fabrication on engine number boards?  Were the number boards a sandwich of two pieces of glass with a metal insert in the middle, from which the numbers were cut out?  If so, what was the metal?  Is there a set of standard plans for the numerals?
