I previously posted here seeking a source for an oversize Fox Butt Plate (to accomodate a spacer), which is not available from reproduction sources suggested. I Found It. Brownells Universal Large Rifle Butt Plate is for all practical purposes an exact match; hole spacing, serations location and number and it is "dead" flat. It is marginally thicker and is missing the circles around the screw holes but otherwise is a good match.
