This is going to be one of my fun tabley posts. I know you all love them so much. Should I start with some general bullshit or dive right into the table? Let's try some general crap first.
There's a good set of Maclay brewing records the Scottish Brewing Archive. They cover most of the 20th century, right up until the Thistle Brewery closed in the 1990's. They aren't in the usual Scottish format, which is a relief. The one line per brew style record. They're a total pain in the arse, as the ingredients are written in tiny letters as column headers. It's one of the reasons we're looking at Maclay and not Drybrough records today.
Though I'm not convinced that the records that remain are the official brewing books. The earliest one in the archive is in a ledger with proper pre-printed pages. All the rest are just scribbled into notebooks. Very classy. They look more like someone's personal brewing book. Many brewers seem to have kept their own records.
The good thing is that the handwriting is legible and they contain pretty much everything I look for, except boil times. I can live with that. At least I don't have to pore over each page with a magnifying glass.
Here's the table:

Time for analysis now, I suppose. First point: note how in January 1939 the names suddenly change from IPA 7d, IPA 6d, IPA 5d to PA 7d, PA 6d, PA 5. It's another indication of how randomly and interchangeably IPA and PA were used in Britain.The beers remained the same. I'm not sure why I keep repeating this, given how little attention is paid. I keep hearing others assert that a Pale Ale is always weaker than an IPA and that the two styles are quite distinct. Neither of those is true. At least not in British brewing.
The range of beers Maclay brewed was incredibly narrow. Just three different strength Pale Ales and a Strong Ale. Note that, while there isn't a shilling in sight, there is another currency unit: the penny. Because these beers are named by their retail price per pint. Interesting that there's not a trace of Mild Ale. It was still brewed in Scotland in this period. Just not by Maclay.
Here are some London Pale Ales for comparison purposes:
|London Pale Ales 1937 – 1938|
|1937||Watney||UK||Pale Ale||Pale Ale||7d||pint||draught||1049|
|1937||Wenlock||UK||Pale Ale||Pale Ale||7d||pint||bottled||0.05||1007.6||1042.2||81.99%|
|1937||Worthington||UK||Pale Ale||Pale Ale||8d||pint||draught||1054.3|
|1938||Barclay Perkins||UK||PA||Pale Ale||7d||pint||draught||0.07||1011.3||1043.9||74.26%|
|1938||Mann Crossman||UK||PA||Pale Ale||8d||pint||draught||0.07||1006.5||1052.4||87.60%|

You can see that they are somewhat stronger than Maclay's Pale Ales.
The attenuation is rubbish, as often with Scottish beers. This, combined with modest hopping, would have left the Pale Ales appearing quite sweet.
Not much to say about the ingredients. They're simplicity itself: hops, pale malt, No. 2 invert sugar and flaked maize. That's it. Though They used several different kinds of pale malt in each brew: Californian, Scottish and from various maltsters, including Baird.
There will doubtless be more about Maclay's beers. Their records are easy to understand, after all. And I've a whole load of them.
