You really can't measure the piston without rebuilding the caliper. The piston 
has a step in it, so that the part you can see is smaller than the actual 
piston diameter. If your pistons are full round at the face, no cutouts, then 
there's no way I know of to be sure of the diameter without taking it apart.

If the pistons have the little triangular retaining plates that look just like 
the ones in the Bentley photos, then there's a very good chance that they are 
42mm. The smaller type 1 calipers used a retaining plate that looks completely 
different.

Unfortunately the latest calipers with the full circle piston faces don't use 
any retaining plates at all.
