The last mention of Bass No. 1 in the British Newspaper Archive is an advertisement from March 1942. Though I doubt it was still being brewed in 1942. I’m sure Bass, like Truman still aged their Barley Wine for a long period, probably at least 12 months. My guess would be that it was dropped no later than mid-1941.
As the Barley Wine that was available during the war had either been brewed before it started or in the early years, I doubt that there was much, if any, change in strength.
I only have details of one wartime Barley Wine: Truman Stock 1. Brewed in Burton, this was the aged component of the blend which made up their No. 1 Barley Wine.

After 12 months ageing, the FG would have been considerably lower.aged component of the blend which made up their No. 1 Barley Wine.
