Fascinating read. I loved the photo analysis part especially. What they forgot is how small Britain is. Everyone overlaps in London, especially back then when Joe Snr was around. The gangs and Mr Bigs were so busy trying to be THE hardmen they weren't known for discretion or intelligence !. Masses of small airfields all over everywhere from WW2. People were coming back and forth all the time from America under many guises.
It reminded me a lot of the current Adrenochrome articles.
I found this little clip as well.
Thanks for posting
