I wished there still where inches, stone, pound sterling ,mph., a milkfloat, the local shop and pub, etc. ,and in Holland the equivalent of that. The world would look much better .

I measured again, in new fangled centimeters, 8.5.....I need a more reliable tape measure

What is the problem , why is it only 2 ˝ you measure?

All is good, when I measured it more carefully it was same as yours......
