Single pocket door escutcheon that seems to match up with the T&B (Taylor & Boggis Foundry) doorknob H-21100 C:1885. Originally had a brass plated finish that has mostly worn off. Feel free to email with questions and/or comments.
Please remember that these are old pieces, many coming from
homes 100+ years old so they will NEVER EVER be perfect and will always
show some evidence of natural wear.
