in brief: Deco style train station, built in 1933, abandoned for many years and refurbished in 1996. The original hand-painted signage was still there in the interior. it could not be preserved, but we opted to recreate the typeface. We re-drew the letters as vectors for our plotters, but they were just shapes. Not a font.
My question is, can anyone here identify this as a font, or was it a lettering style of the sign painter who painted the signs? (ignore the numerals, they are Helvetica. The letters here are dimensional so there's a shadow cast, which is most apparent on the top two lines.

Thanks
