Sacrilege Ted. The entire world knows the Model 12 is the perfect repeater. Sellers often pretend to not know what they have but whenever I offer them half the real value they all suddenly know not to sell. Its trolling for suckers.
I do not pretend to know the Darne, Darne, Charlin guns well and have a complete lack of grade understanding. I know you that they are cousins and look like similar guns but not all created equal by any means. Years ago I almost bought a very pretty 24 gauge Darne in a fairly decent grade. That was until I looked at the ballistics of the 24 and decided both the 20 and 28 would do the same thing with a lot easier time finding ammo. I still wonder where that 24 is from time to time. Due to lack of use it was just like new and most likely still is.
