There is an enormous variety of centre door knobs fitted to Victorian and Edwardian homes though to the between the wars period. Most are either cast from brass or cast iron.
There were many foundries producing them including Archibald Kenrick & Son in West Bromwich, UK which was opened in 1791.
The original foundry closed in 1965 however Kenrick continues to manufacture today as part of the Spire Manufacturing group.
We always have a selection of original centre door knobs and other door hardware for purchase.
