Promo you could be correct, but a difficult restoration if the W&S holes were enlarged to remove the threads - also the "Hatcher hole" on a W&S scoped rifle is not the best kind of a restoration. It is kind of like the anneal receiver color on a prewar M1icon rifle restoration. Holes can be fixed.
I had a friend that found two barreled actions at the CMPicon, both receivers had the W&S screw holes and plugs, he was able to restore these rifles (but is still looking for a better late 1917 barrel). I did mill the left inside of two stocks for him (used a 10mm ball end mill if I remember) so that the actions would fit with the W&S brackets. These receivers did not have the Hatcher holes.
