White lettering on black fabric - Western Region (London) 1950s.
Fairford closed in 1962 and Lambourn closed in 1960.
Note that Princes Risborough is mis-spelt Princess Risborough. It's probable that this blind was fitted to Class 121 units from new, most of the early photos on the Railcar website match the typeface and positioning of this blind. 55027 photographed on 15/08/1981 is most certainly carrying the blind, and you can just about see FAIRFORD above GREENFORD. It's likely that there was a similar blind produced in the early 60's - Lost Lines, London by Nigel Welbourn - Page 103 shows a photo of two Class 121 units passing each other at Colnbrook. The unit on the left (55029) is showing STAINES WEST and the unit on the right is just showing STAINES. I'm positive I've seen a photo of a unit just showing UXBRIDGE on the blind too, but I can't put my finger on where at the moment.)
