Sign - font ID

I would appreciate help to identify the font on this sign.



It looks like Delphian Regular by Robert Hunter Middleton (1928), currently available from Linotype in Mac Postscript Format
There was also an older version from Agfa named Delphian CG but I can't find any legitimate source to acquire it.

EDIT: It's also available from Monotype in both Windows & Mac Postscript format

I found it using Find my Font -

Thank you so much for identifying the font ... and for sharing your source. Your help is appreciated.
