Congrats, (maybe?) I saw that No3 Mk1* (T) A stock on U.S. Ebay and wondered how may viewers knew what they were looking at; or how many forum members noticed it.
That was for a pretty specific model of rifle and I was hoping it would go to a good home. It was very, very, reasonably priced for what it was, but I personally knew the odds of finding the correct project action for it unless someone had it already.
If you were looking for a regular Winchester stock (that is not Drill Purpose cut) they do come up and they can be found if you check the markings. That is a very unique stock and is quite a mismatch if I have understood you correctly.
Edit: I just looked at the listing and the seller again and the seller parted out this entire rifle, chopped receiver included, including the rear No3 Mk1* (T) A aperture rear sight among everything else!
And a complete No4 MkI (T)!
For tenths of pennies on the dollar!
