The first pleasant surprise was how little it was out of true with just a slight twist, high left far corner and low right near corner, and a small belly down part of the middle. I've removed the twist and the belly and now it is just a matter of digging out the #8 and finishing up.
One other, maybe not a surprise, but pleasant is how much easier it is to plane on a 800mm surface vs. a 900mm surface.
I will add a crochet planing stop to the left end and see if I can find the old deadman. If it is gone (I never throw anything away unless it is something I will need later :-)) I will make another for use with the crochet.
