Can anyone identify this:
it's steel, 19/32" thick, 12_1/8" x 12_1/8" square and the groove centres are 7/8" from the edge of the plate, and I found it in my loft.
Seems far too carefully made to be just a lump of steel plate.

Just guessing: some sort of damper plate, the grooves being the result of it sliding up and down.

Template for cutting roofing slates

It would be terribly heavy for use on a roof. Very dangerous.

Looking at it I'd say the grooves are almost certainly machined, not worn.

Cut them at ground level then.
Jeweller's bench block?

I do have a slate roof, but the slates are oblong rather than square, seems something of an over kill for a slate template, it weighs 25lbs.
My feeling is it's a reference plate for something, as I mentioned in the OP the centre ridge of the double groove is exactly 7/8" in and the centre of the single groove is exactly 7/8" in.
I don't know, but I think it would be pretty good for making crêpes on.
Is it featureless on the other side?
Suicial Frissbie?
yep
Right, so it's for French roofers to cut slates at ground level, and make their lunch on.

So what was it doing in my loft then?
It may be a surface plate, if the other side shows signs of maching or lapping to make it very flat. If it is, it would probably have some value, which is the only reason I can think of for someone keeping it. It doesn't show any sign of rust, so it is more likely cast iron.
Otherwise it fairly worthless scrap.
We were somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember bof saying something like:
I think it's an inking plate.

It's where you put things you don't want to throw out but have no immediate use for.
