Copperplate Gothic 33 BC  Suggested by Heron2001 
Linoscript  Suggested by elzadra 

Myfonts.com is funky right now - I believe this is Copperplate 33 -

but can't see it online...

I've tried to Copperplate Gothic, but it is not, it is as alike.

There use to be a font named Spartan Two Four or Spartan Four Two - if you can find it - take a look.

I not found it. =(
