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.

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.
