copperplate script - pre digital?

I looked at Bowfin's website (very helpful I might add) but cannot locate this font. Pre-digital?


Sterling Script - similar -
(Sterling Script has alternates too)

Gracia Series 40 - similar -

Similar yes, but those look like so many other scripts. The Caps are unique on this sample

The bouncing baseline (the i is raised) suggests this was either rub-down lettering or manually set display phototype. A quick check against the more popular Filmotype film fonts doesn't find a match. Certainly looks pre-digital.

Any specific info on where this came from (North America or elsewhere) and how old it might be?
