B-Square makes a scope mount & rings for the 1917 Enfield, including the Eddystone.

Looking at the buyer comments/reviews, and thinking about the 1917 rifles, I would think additional mount screws are needed, and that the receiver & bridge needs to be spot annealed before any D/T, due to the exceptional hardness.
If the B-Square base doesn't already have mounting a screw hole just ahead of where it passes over the hole in the bridge, it'd most likely possible to drill new holes in the required location.
