Can't help with post WW1, I have a 375H&H belted mag made 1913, Magnum Mauser action.

However, I think the later Monte Carlo stocked would be better with a scope (mine is not drilled/tapped for scope use).

Some certainly look very nice. For quite a while H&H presented very poor photographs of their rifles and guns for sale which didn't help perception of their quality.

I have seen some very nice magazine rifles, although admittedly many were pre WW2.

Cheers, Chris
