As seen on Facebook. I believe chdot does not hold a Facebook account book with which he can view the bike but I have seen for sale a:
Triumph Gentleman's Roadster circa 1950. Looks in lovely condition from the photos. Originally has Sturmey Archer 3 so replaced in the 70's with a 4 speed. Everything else looks vintage.
Its on the Bikes For Sale or Swap Facebook page. For sale on Teeside.
