Could you measure the width of flats on each of the base plates? It would be nice to have empirical values so that Tuckaway owners can compare.

Simon: I love your avatar! I even have a Wallace & Gromit shave kit.
Anyway, the flat part on the top of the baseplate of my New Improved Tuckaway measures about 13mm compared to 15mm on my English NI Richwood.
I think Cornishman's observation is one of the most interesting things I've read about on this forum for months. I can't wait to compare my two NI heads to see which one I like better.
