Re:
This thread is a bit dated, but I wanted to contribute as I have this same bicycle (though originally in "British racing green" but with the gold lug lining) and have not seen another since acquiring mine. If going by the dates on the headset and bottom bracket, it is from 1973. I had a framebuilder named Christopher Igleheart (known for his rigid MTB forks here in the States) make a few modifications - respacing the rear triangle to 126mm, crimping chainstays for fat tire clearance, moving bridges for fender clearance, cantilever posts spaced for 650b wheels, brake cable stops and water bottle mounts added.
The downtube transfer is from H Lloyd, the original - a large oval thing - was a bit ghastly! It had the same diamond shaped head and seat tube transfers depicted in your photos plus a worn Reynolds 531 transfer near the seat lug. All restoration decals and paint by John Bowe of Underground Cycle, New Hampshire. John Bowe painted for Christopher Igleheart. He used to be Ted Wojcik's in-house painter before going solo. He currently paints for Boston framebuilder Peter Mooney.
The original components included a Campagnolo Record headset and bottom bracket, GB handlebar/stem, Weinmann calipers/levers, TTT seatpost and generic replacement saddle, TA Professionel crankset, Shimano Crane rear mech, Huret Jubilee front mech, Normandy Luxe Competition hubs laced to AVA clincher rims and a Maeda (SunTour) 5spd freewheel.
Replacement components included Grand Bois stem/handlebars/decaleur, Mafac cantilever brakes and levers, Brooks Pro saddle, TA Pro 5 Vis crankset, Huret Jubilee rear mech, Campagnolo record hubs laced to Velo Orange Diagonale rims, Honjo fenders, IRD 5spd freewheel.
This machine served as my primary randonneuring bicycle from 2012-2015. In that time it saw countless miles, completing many Brevets and weekly century and 200k rides. It is being restored with a mix of the aforementioned components and will be for sale in the coming months. Just thought I would share!
