A W&S 700 is what triggered my distrust of tumblers with integral strikers. I'm told a few exist with disc set strikers, but, have never witnessed this.
Maybe it isn't true.
That said, a simple boxlock, well finished, with touches like double triggers, and disc set strikers, a gun that is actually built for a shooter/hunter, is a great find. The majority of these are English or Continental guns, and always will be.
Low maintenance is as good a thing on one's guns as it is on one's wife. Glitz only goes so far.

Best,
