Oak and leather are fantastic, BUT before you spend the money consider this :-
Whilst an Oak and Leather may look fantastic in the gun room proudly showing off your gun, they are blooming HEAVY, and if the case is for travel I would rather have a traditional lightweight leather or canvas and leather hard case. They are also less susceptible to damage. Yoyu drop a lightweight case - it might bounce. You drop a heavy Oak and leather case and its a bl**dy disaster, shattered wood and loose joints etc etc.
