Not all of those varieties have continued to be grown. A couple – Northern Brewer and Brewers Gold – are still pretty popular.
I’m not going to pester you with too many words. But I will make a few remarks. The alpha acid content of Early Promise is really variable. From 4.38% to 7.71%.
Oh, and make a quick comparison with modern English hops.

One of the two 1953 examples of Brewers Gold has an alpha acid content slightly higher than the modern upper limit – 8.8%, on a range given as 5.5% to 8%. And the Northern Brewer examples are all towards the top end when it comes to alpha acid.
More on hops soon.

Pride of Kent sounds really interesting. Consistently higher Beta acids (and fairly high at that!) than Alpha acids! I wonder what that would have been like after a bit of aging.
