Late 70's, UK, kinda similar to Windsor

I'm having troubles identifying this font. It looks somewhat similar to Windsor, but is off in many details. Does anybody here know this one?


It's so close to Windsor D Extra Bold Condensed (myfonts link) - apart from the F and the tips of the Z - that it looks like someone just rounded those off. The new replicas use the original font though, but you probably know that... :)

(Just passing through searching for Windsor-related posts...)
