My wife bought me the Silent Paint Remover for my birthday recently. I immediately tested it out on the linen closet in our hallway (shown below). The paint is coming off nicely, but it forced me to go look for new hardware. The hardware that is currently on it is definitely not original. The entire hallway is as white as possible, white walls, white trim, white hardware. The laundry chute in the second picture is on the opposite side of the hallway.
For some unknown reason, I decided I wanted octagonal crystal knobs with brass bases. Also, I needed 9 that matched, and they had to be antique. My first stop was at Guilded Salvage, which I think is a great store. I found a set of 9 yellow-green uranium glass (actually made with uranium, type it into google) that would have been great. Unfortunately, they were $65...a knob. I decided to pass.
After searching dozens of salvage websites, I came across www.coolstuffiscoolstuff.com, aka Architectural Artifacts in Toledo, OH. Incredibly, they had exactly the hardware I was looking for, 6 larger glass knobs for the drawers and 3 smaller ones (2 for the linen closet and 1 for the laundry chute). They were extremely helpful and significantly less than $65 a knob. Hopefully I will actually finish stripping the paint so I can install them.
