Don't overlook these guys. White Chapel Ltd.
is a wonderful resource for antique style cabinet and furniture hardware. They sell high quality brass hardware, and their selection is outstanding...
We enjoy a perusal through their catalog even when we aren't seeking anything in particular. It gets creative juices flowing and it's inspiring to see so many fine hardware pieces presented so clearly. This is one catalog we recommend getting a hard copy of. Their wares are shown photographed on a gridded background that communicates the hardware's scale at-a-glance.
