Great photos of Lt Hall's 4 Tp in Tilburg Alex!
All 5 Crabs are visible, led by Lt Hall's. He is the one with the moustache, leaning on the gun on this photo:
Just ahead of his tank is another Sherman which must be Capt Squirrell's command tank. The stowed jerrycans on the left rear of the tank might mean it is the same tank as on IWM B10819, although of course the other command tanks in A Sqn might have used the same stowage method:
Finally, the second Crab in the line might have a name on its side, but the graffiti and low quality of the photo make it completely illegible:
