Hi guys--------- have just seen these on For me-Bay }------http://www.ebay.co.uk/itm/External-Dial ... 6786?pt=UK -------

Quite a a nice tool Alan, but they've missed a trick!....they could easily have had probes on the outside position on the measuring arms too, thus allowing internal measurement to be taken such as comparing the bore diameter to the outside diameter of a piston.
