done!
i've chosen the first firm.
they are the most reactive and they already have the pieces between hands.
tomorrow or the day after i go to Bordeaux to see them.
this could be made at the beginning of August I think. i hope!
I make 10 pieces, enough for those who has contacted me.
price maximum will be 53€ (47£) + transport. (i shall negotiate to decrease it

)
bye!
"i'll be back"
p.s : we gonna try to make a (little bit) longer chassis.
a carbon one (or two, or three, lol!), more flexible for dusty/sleepy tracks.
but boxes first...
