Can you find this Font?

I've attached a pic of the font I'm looking for.

I've found numerous that are close, but none that are exact.

So, can anyone help find this font?

Thanking you in advance.

I wonder if it was hand-lettered?

Believe it or not, before digital type, type was either metal or hand lettered. In the 40-60s many headlines and larger display type for ads and billboards was hand-lettered. And so there was latitude for lettering artists to take liberties with existing typefaces. Your sample might be based on a traditional typeface with some modifications made.

Rik, it is probably not a font as it was designed by the College of Arms Scriveners early 1950s.
As such, a full font might never have been considered. ER is the cypher used in Scotland as it disputed Queen Elizabeth II was the second as the First was but Queen of England.
In England EIIR is used.

Acorn

no such hair splitting in our new carolean age I trust....

I agree with acorn - if this is the official Elizabeth Regina symbol, the chances of it being a standard font are remote...

Thanks for the feedback, guys.
Much appreciated.

As you say, it may not be a font, at all.
