Recently we have been discussing in the forums Dr. Browns various travels through England and France in the mid 1950s. I have in my archives one photo that appears to be from that period, but I have been unable to identify the exact location. I have shown it to one expert on the time/subject, and he has identified it only as "1950’s, definitely England" and "definitely MI5. That’s how I know it is in England."
I’m not sure why it is important now, but it seems it would be very useful to get a positive ID on this location. I have posted a larger version of the photo here in the forums. If you think you can correctly identify this location, please post your answers there.
