I found the attached on the Tank Museums' Tank Chats.
Tank Chats No. 52 Sherman Crab Flails. At about 6.15 minutes is the image of SCHIET OP, which I am informed is Dutch for Hurry Up, via replies to my post on WW2Talk.

I would appreciate any thoughts or comments on the validity of the name and regiment.
