I purchased these knobs for an addition on our 1850's house. They cannot be told from the originals, except for the upgraded allen head set screw. The doors that I made are 1 1/8" thick to match the originals in the house. The supplied spindle can easily be cut down with a hack saw, or order a different size as another review noted.

The knobs and rosettes are very nice. But the included spindle is 4.5" long, which is way too long for a standard 1 3/8" door. I had to buy standard 3.5" spindles separately. So -- if you buy this, and you have standard doors, be prepared to buy spindles as well.
