I thought I might weigh in here as this era Raleighs are my favorite vintage bikes and I have had a few hanging from the rafters over the years. Here are my recollections based on the models that I have owned: <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> Pre-war RRA \u2013 Resembles a postwar Clubman (like Alan's) but with very finely fluted cranks. Fluting around circumference of BB boss and both sides of arms. Quite lovely. Chainrings may be the same. (\u201939 RRA)
Post-war RRA \u2013 Elaborate finely forged cranks as shown in Peter\u2019s pictures. Fragile arms and rings as I have seen broken examples of each. Reg Harris went for a Williams/Stronglight combination IIRC. (\u201948 (2), \u201949, \u201950 RRA's)
Clubman \u2013 Similar to prewar RRA but less elaborate fluting on cranks, typically front of arms only. (\u201949, \u201951 Clubmans)
Lenton Sports \u2013 Similar to Clubman but no herons on chainrings with fluting on front of cranks. (\u201950 Lenton Sports)
Lenton Tourist \u2013 Similar to Clubman with herons on chainrings but no fluting on cranks. Just like Alan's although this model is quite rare. ('51Lenton Tourist)
Based on my experience I would say Alan's chainset are likely from a postwar some variety Lenton or Clubman.
I love these bikes....
