Mark, that is a really nice Daly and looks to be in excellent condition. A great find and a great price.
I'm going to show a couple of pictures of my Daly and maybe this will help explain what Eightbore is referring to when he says "etched". The first picture is the original barrels to my gun and they are "etched". By that I mean they have a very definite texture to them. They are not smooth. BTW, these barrels are in original finish, they have not been redone.
The second set of barrels are what is called "Manufacture Extra". This nomeclature is from the company catalog of (forgive the missing accent marks) Manufacture Liegeoise d'Armes a Feu. Portions of this catalog are printed in Manfred Sachase's book on damascus steel. At the time of manufacture it appears that these barrrels were 5 times more expensive that the cheapest barrels from this company. This set of barrels have been redone in the classic black & white.
