Thank you for visiting! Condition may include any of the following: antique wear, patinas and or tarnishes / rust spots, stains, pitting, bends, micro-cracks, modifications (known or unknown), old tape or other material attached to key and minor defects. Non-key items used in pictures for display, backgrounds and measurements not included or available for sale unless otherwise noted in the description. Only the keys seen in the pictures are included unless otherwise noted. All dating of keys is estimated since keys can be reproduced at any time. Key length sizes are sometimes rounded off to the nearest 1/16 to 1/8 inches. Keys are generally not cleaned to maintain antique nature. All keys seen are steel, iron or other non-brass metals unless otherwise noted. See our other 100+ listed keys! We do not suggest purchasing any key as a replacement unless you know the key will fit. The problem with older keys and locks is that the mechanisms and keys often change due to wear. In addition, key measurements can vary greatly due to small differences in bit cuts, depth, shaft diameter and sizing due to metric vs. Our square end keys, including clock keys are sized by metric standards. I suggest consulting a locksmith to confirm lock / key fitting. Item(s) must be packed in equal protection as received and be tracked/insured (to prevent loss). Non-Sale Items: Items used for backgrounds, props and sizing (rulers and coins) are not included unless otherwise noted. It has been our experience that keys are not seriously damaged when packed as a tight group. Valuable keys or single keys are usually packed individually. Special packing is available upon request, but large groups of common keys cannot be packed individually due to time restraints and postal box size and weight limits.
