The H&H gun was made in 1935. That was the only time they designated the model as Centenary (Henry Holland opened his tobacco shop in 1835) Looks very similar to a gun I imported several years ago and sold back to the H&H NYC branch. Interestingly the Wall thickness was .014", yes 14thou. I pointed this out to Guy Davies as he looked over the gun. He responded "Don't worry about that that's the way we made them"
