I have been using Dyson hand made hinges for years in the gun boxes I have been making, but Peter is quite elderly, and isn't keeping up with the demand.
There is a very high quality hinge made here in the USA, and I have tried a set to see what had to change to fit them. They are called Brusso, and are very nice, but, like Peter's, they are pricey. They come in three sizes.
