I keep reading about little disappointments -- locks tarnishing, etc. (This is not unique to the LV forum -- there are plenty of gripes about chips on the Paddy locks too). I'm wondering -- for any of you who might have an LV from the 70's, or 80's or earlier -- were these bags made differently? Different canvas or leather? Anything different? Is a Malletier better / worse than a current model? Opinions, please . . .
