I sometimes wonder what I would have done had I not discovered the Whitbread Gravity Book. It's so packed full of information on other company's beers. Truly a wonderful resource. But there are other Gravity Books, too. Truman, William Younger and Thomas Usher all had ones of their own. Albeit not on quite as grand a scale as Whitbread's. They do provide extra information. Especially in the case of the latter two on Scottish beer.
I came across this price list from the Northampton Brewing Company while performing one of my regular trawls through the newspaper archive looking for "Mild Ale". A strange hobby, but a harmless one.
It's unusual in that in features a bottled Mild Ale, something that wasn't very common. Mild was rarely available in bottled form, though often because it was sold under a different name such as Family Ale or Brown Ale. Though that can't be the case here, as the Brown Ale costs 1d more a pint.
Now this is where I'd be stumped without the Whitbread Gravity Book. What were the relative strengths of Northampton Brewery's Mild Ale and Brown Ale? No problem.

The Brown Ale was quite a bit stronger than the mild Ale, as you can see. What of their other beers? Jumbo Stout is easy, as I have an analysis from about the right date. For IPA, though, I only have one from after the war. But, by looking at that and the BAss and Worthington analyses, I reckon I can make a good guess: low 1050ºs.
I'd expect it to be about the same strength as the Burton versions, as it's just a hlfpenny cheaper for a half pint. Bass and Worthington always sold at a premium price. If you're wondering why the ones in the table are so much cheaper than the ones in the price list, there's a simple explanation. The table has draught versions.
Jumbo Stout, despite it's reasonable OG looks like awful value for money due to the crap degree of attenuation. Which leaves it not really intoxicating.
