^^^^^^+1 the slight difference in radius will be accommodated by the mounting position and the stays, (there is about 4mm difference in radius)
I think I understand now
If I was to order mudguards for a wheel size no smaller than 700x28 - 38 it would be fine
What does the 28 mean
Thanks
Chain reactions web site list the size's stupid http://www.chainreactioncycles.com/sks-bluemels-road-mudguard-set/rp-prod84326
I think it is this that is throwing me 700 / 35, 700 / 42, 700 / 53 ?

The 28 is 28mm, representing the smallest width of the tyre the mudguard is suitable for. The 38 is 38mm, the biggest width tyre the mudgaurd is suitable for. Like socks that go from size 7-11.
Chain reaction's site is showing the actual mudguard width. Wiggle show both tyre width and mudguard width. For an inch and a quarter (32mm)m tyre, I'd say the 45mm wide guard is the one (although Chain reaction have it down as 42mm)

A 27" wheel is 630 mm diameter (to the bottom of the bead) and a 700c is 622mm so the difference in radius is 4mm (which is why often it's possible to convert a 27" wheeled bike to 700c by simply moving the brake blocks down the arms of the brake calipers)
The mudguard mounting points on the frame are slightly further away from the axle on a 27" wheeled bike but only by roughly 4 mm or so and it is easy to flex the mudguard out by this much. A 700c wheel with a 42mm tyre is bigger overall than a 27" with an 1"1/4 tyre.
