Thanks a lot Tom, that's very kind of you.
I also read that you are a "M2 fan", so am I.
I think the M2 is one of the greatest and I also have a M4...
I am very interested into these small cranks I saw on your M2s on Hans
Pahlen site. Where do you find these? or do you make them yourself? How  do
you adjust it on the rewind button?
Thanks again,
