Thanks again for the great information.
My father owned this bike and lived in Reigate up until the 50's at which time he purchased a larger Ariel and made a sidecar for it. There are photos but they do not show the bike very well. He always had Ariel bikes as far back as I can remember.
My fathers name is Thomas H. R. Smith, his brothers name was Jack Smith, both brothers were into bikes during the 40's and belonged to the R.R.N.D.M.C. I have contacted this Reigate/Redhill club but they have no records going back that far?
If any members are able to locate this exact bike or log book I would be more than willing to pay a premium finders fee.
