Yes, OPTI Kite Bold looks like a good match, many thanks indeed!

Hello
I am trying to identify this font, which was used in an advert from 1981, so pre-digital. It is not the greatest quality image, from an online newspaper archive, so apologies for that.
I have been through my old copy of the Mergenthaler Type Library with no joy, so wondered if anyone had any ideas? Distinctive lower case e and s, and I am sure I know what it is, but cannot place it...
Many thanks!
