The total number of quarters in the grist remain the same, but there’s more crystal malt and roast. No need to guess why this might have been, as there’s a note in the record explaining it: “N.B. New proportions for coloured malts to make up colour due to gravity reduction.” Which makes sense.
Another change to the grist compared to 1941 is the use of lager malt rather than pale malt as the base.
That all the malt was being added at the start of the mash is confirmed by this record. What could the reason have been for that? Aside from that, the mashing scheme was much the same.

Just two types of hops, Belgian Saaz from the 1939 crop and Goldings from 1941, both cold stored.

At a homebrew scale, I'd be nervous about doing a single mash at 158F and ending up with unfermentable wort. I see this one doesn't attenuate, but still--what if it stuck higher?
How did they raise temp after the protein rest? Underlet? I wonder if a lot of conversion happened on the way from 126F to 158F?
