Thanks for the replies guys. I bought both of these because I like to experiment with new set ups and innovative niche products. The only real way you can encourage such efforts is to buy the early products to fund some further development.
No pics from me Dave as I have an existentialist approach to bikes, seldom take photos and of course it's different now. Googling "Berthoud shifter" should give you what you want.
Shifter works well with some self evident issues around cable sealing, but it's not a problem for UK road use. Mine is marked because I had to wrap cloth bar tape around it to get a grip in the wet. No one else makes one to do this job except Comotion and theirs is a stupendous diameter as they've made it for 31.8mm, and even more expensive. Danneaux has written about this one.
A used on would also go on a drop bar end and not cost much more than a hubbub bar end adapter
Thorn also sell a converter to allow use on 22 or 24mm bars
http://www.sjscycles.co.uk/gilles-berthoud-gilles-berthoud-clamp-ring-for-gb-twister-for-rohloff-shifter-prod32760/Bars are nice quality but very deep drop, too deep for me as it transpires
I seem to recall reading in some Thorn blurb that they could only get one size and shape done due to cost constraints. I just wish they'd gone for 42cm compacts.... No one else addresses this issue...
Happy days
Ian
