Extra details Original finish is as purchased from Mercian in 1976. I first saw this machine a few years ago and fell in love with it.  I lost track of the owner but recently made contact and he was willing to sell knowing it would be kept and looked after. For some reason he had hand-painted over the front forks with red paint and I spent hours carefully working it back to the original colour.
Allen key fitting for seat post clamp on seat lug is Imperial 7/32" as is found on some early machines before metric became the norm.
This is one of my 'Fixie' indulgences and not constrained by the sites normal parameters - I can get away with it being 'the boss'!

Stronglight 49 5-pin alloy cranks with TA 49T alloy ring and Shimano SPD pedals
There is only one position on the 5 bolts which will give equal spacing of the arms either side of cranks
Check this before installing and tightening all the bolts - been there, done that!

The latest 'bling' on this machine is courtesy of  Stuart Henderson who has drilled and painted
the chainring and brake stirrups for me.  I have completed the job with a silver chain and chrome sprocket.
