Info Sought on the Oxford to Princes Risborough Line

For an upcoming 00 gauge model, I am looking for information on the Oxford to Princes Risborough line, in particular Thame, in the period 1958-63.

I have the R A Cooke section 27 plans, the Middleton Press book and the Richard Lingard Book, plus all the GWJs. o what I am after is the more obscure magazine articles and personal memories?

Any help will be much appreciated
Many thanks

Paul

 

I should have included that I am also aware of, and awaiting the arrival of the C.R. Potts book!

Thanks
Paul
