It started when someone posted this John Smiths price list from 1971:
I remembered that I had a wealth of analyses of John Smiths beers from the Whitbread Gravity Book.

There's a personal connection with one of these beers. Milk Maid Stout was a Warwick & Richardson brand. And the beer my Mum used to drink. The label appers prominently on the cover of The Home Brewer's Guide to Vintage Beer.
There's not a huge difference between the prices in the two lists. Take Golden, for example. 24d = 10p, meaning it had gone up 4p between 1964 and 1971. But that would soon change. The early 1970's were a time of high inflation.
That's it. Just a pile of random crap. Oh, except one last thing. Golden and Bitter were probably the same beer. Note how much worse value the keg beer is.
