Sherman Crab T147955 “Avalon” Overloon. Regiment? Damage?

[Alex van de Wetering]

The dark rectangular mark could be the name or another marking painted out, that happened quite often after a vehicle was struck off strength

I can confirm that it actually says "Avalon" in white in a picture of it early in it's museum life. I have no clue why it shows up as a dark patch in later pictures, as this was already when it was a museum exhibit.

Summing up, we would need to get access to the war diaries of the two regiments mentioned above and see which Crabs were lost due to mines and/or enemy fire.

I was hoping the war diaries were to be found online somewhere, but no luck so far. I think I will send a request to the UK National Archives.
