Be better off doing up an old 531 touring frame with Nitto moustache bars and the like
Speaking as the new owner of an old 531 touring frame (Fred Williams, early 80s) which will have moustache bars whenever Hubjub get some in, any more suggestions for 'the like'?
I think the Nitto Albatross bars are more similar to the ones on the Guvnor than the Moustache ones.
Apart from that, some Brooks grips, a Brooks saddle (matching, natch), single speed / fixed rear wheel and matching front: get some silver hubs from On-One and some silver rims (Mavic Open Sport are alright and pretty cheap) and build them yourself. Reverse action TT style levers and canti brakes, if it has braze ons, or Alhonga deep drop if not. "Woolly hat shop" on ebay is a good place to get canti brakes. Chainset from ebay or a forum, just put a single ring on it. Stronglight rings from Spa Cycles are cheap if not exactly round. Quill stem from ebay or get a Nitto one to match. Fat tyres like Schwalbe Marathons.
Sorted!
My Hill Special is a little bit like that, with moustache bars and old Campy levers but the wheels are a funny size (26 x 1 3/8th, 590mm rims):
