The scope mount on your rifle is by Tilden, the same company which made the "starboard side" conversion for the pre-War Model 70 rifles. It is a quality product.

If I recall correctly, the late production Model 30 Express rifles were made cock on opening, rather than retaining the cock on closing feature of the P-14/M1917 Enfields. Does your rifle cock on opening?

The stock features appear European to me and remind me of features I have experienced on pre-War commercial Mauser sporters, including the cheek piece and the length of the fore end. I have such a Mauser, with both features.
