My Windsor Carerra also uses the 26.2mm size post, while my Pro uses 27.2mm.
That brazed-in shim might have prevented the cracks that formed to either side of the slot in the seat tube on my Windsor Pro. They milled the metal too thin for clearance with the binder bolt, so I had to terminate a couple of cracks with a 1/8" drill. I think I caught it just in time as the cracks were moving out and up under the stays. That was 1500 miles ago. The bike was an old throw-away at Goodwill, fully chromed under the peeling paint.
