They are different companies. A Harrison is owned by Bulmer Lumb, the same company that owns Taylor & Lodge. It gets especially confusing given that Harrisons of Edinburgh is a third distinct company with the Harrison name.
Yep, you are very correct. I have asked them about their Arthur Harrison flannels. It is not from their own production (Harrison B), nor it is from Harrison of Edinburgh.
I don't know which part of my word entails Harrison Burley is the same company as Harrison of Edinburgh, clearly their respective prices reflect the truth.
Still, they are very good fabrics and it will be your loss because of their 'silly' name.
The chambrays and traditional oxfords are 44/45" wide, and cost $7.95/ yard if you buy up to 14 yards, and then $4.95/ yard if you purchase 15 yards or more. The pinpoint oxford is the same width, and costs $9.25/ yard for up to 14 yards, then $6.25/ yard for more.
They also have a wider oxford at ~60", which is of course cheaper, but I don't have any swatches for that (it's $6.25/ yard and $3.25/ yard).
P&B has a three yard minimum. They didn't seem to mind that I was a private individual, but they did seem to assume at first that I was a business. I think they've never had to make a policy about selling to the public because not that many private customers call in. Either way, ordering seemed fine.
I haven't had the shirting made up yet, so I can't say how it wears. In searching around for info about the merchant, I found an old post at AAAC by Shirtmaven, who said that P&B's Japanese oxfords were pretty mediocre. He certainly knows more about cloth than me, but FWIW, I thought the 44" width traditional oxfords was really handsome, so I bought 15 yards.
Can you let us know the cloth numbers for each reference?
