The "liberation, somewhere in Holland" picture wasn't taken in Holland at all. I've just checked Getty and this is the caption:
22nd July 1945: Excited Berliners cheering Winston Churchill as he left the 'Winston Club' a club for troops in the Kurfurstendamm which he had just opened. (Photo by Hulton Archive/Getty Images)

Bard (Google AI) tells me that "Churchill was not accompanied by any British military unit during his visit to Berlin in July 1945. His entourage consisted of his daughter, Sarah, and a small group of advisors." Looks as if there's an MP on the bike.

Not too sure Ian, how did you find that it came from London? The last known whereabouts was Bolton, North west where it was purchased by my dad in the 70s
