Per Dallas, DMBs improvements over the Dickson are as follows:
1. Better steels (Alloy vs. Carbon) the main improvement
less distortion in hardening
internal parts are tougher and more resilient
2. Strengthening the Fore end iron at the rear of the knuckle by using a radius instead of a sharp corner.
3. Constructing the barrel lump slots in the action body without drilling through the bottom of the action. This allows a shorter trigger plate than in the Dickson and more strength.
4. The addition of an integral pillar to the upstanding bar on the lockplate there by strengthening the lockplate.
Soooo, basically nothing is different mechanically from the DMB vs. the Dickson RA. I knew that, but I was wondering if Cz had some new info regarding the design that I might have missed. Now take into account the new Dicksons being built in Dunkeld and all of those improvements are sixes. Most gunmakers acknowledge that the old Dickson is actually superior to the DMB version in regards to fit & finishing of internal and external parts. A small bit like a top lever is a good example, the sculpting on an old Dickson is much more artistic and eye pleasing shape to the eye aka it took more time to do it that way.
The old MacNaughtons were indeed lever cockers, that is why the top lever is so elongated....it was to increase leverage to cock both locks. The later guns are/were barrel cockers.
