Yes we have had many enquires.  We have now made 10 b170 check out site under common spares.  I am lucky that my factory is next to brooks in brum.  I have been in their and theirs not much left for the old bikes.  So we have an original b170 and a b180?  Seat to copy from. The frames have been laser cut.  The fasteners have been machined and the four types of springs are wound.  Seat pan dies have been made and have stamped 50 pans so far.  Seat clamp has been made from a lost wax casting also available under common spares. Plus see the new B100 leather tops we have had made now for early veterans.
