The 1973 Ti Raleigh Team used Mk 1V Professional frames in the new Team Livery with Weinmann 500 brakes, Nervar cranks and Huret Jubilee gears, not sure what the other components were used..?
Looking at the op's pic it appears to have a tang on the inside of the front fork, could just be paint loss though, that marks it out as possibly a team issue frame rather than a standard mk4
I will try get back out and see this bike and hopefully purchase it. If not I will get some more detailed pictures of it at least. Thanks for all the info
