For quite some time we have sold a great line of vintage style knobs from Nostalgic Warehouse. There are many knob and backplate styles to fit your historic home, but up until now we have just sold the complete locksets. We now offer all of the misc back plates and knobs for sale individually. If your old mortise box works fine but your old antique doorknobs are falling off of the spindles, you can now just buy replacement doorknobs and spindles if you need to.
