I dove in to this. What I found in the UK (Amazon.uk) was 1 lb, 2 lb, and 3 lb loaf pans. There doesn’t seem to be any standard size for what a 1 lb pan actually measures. I also found this discussion.
John, how does this line up with what you see in the shops? I don’t recall you being a particularly keen baker. On that note, how about casserole sizes? In the US, in inches, we see a lot of 9x13, 9x9, and 8x8.
