Extra details This R O Harrison was acquired  on 17.12.2012 from Colin Colrop who purchased it from the original owner, a keen racing man, in 1958.  The frame had recently been sprayed with 'rattle-can', there was no trace of original paint on it and it was built up with non-period equipment. Colin remembered the down tube transfer only.  The frame has now beens resprayed by Marion Vaz in Salmon Pink with white head tube and lug lining, we were able to retain the chrome ends which is all that remained of the original finish. I am having discussion with the Marque Enthusiast .as to which model this is, old catalogues are indistinct and it is not possible to identify the lugs from them.  Lyta was the top model at this time and this frame has very elaborate lugs compared with others of the era. I have however seen images of R O H frames with elaborate lugs plus cut-outs, research is ongoing!
