Finally got my order in.
Two T-bird pickups, with rings, are making their way to Edinburgh. The total cost came to $115.30, as I specified a slightly quicker delivery time and I ordered a ring with each pickup. I'm slightly frustrated that these didn't show up on Ebay if I went through the UK page, though I see that chap is selling empty pickup shells and rings again.
I'm guessing these are the lower resistance pickups, which works for me!
