Antique Steam Era Maine Central Railroad MC RR Caboose Key Skeleton Double Ring

Maine Central Railroad Caboose Key 3.61" length x .90" handle head width Brass caboose key for MC RR. The bow is oval and marked well. It has a bit of verdigris. The shaft of the key has several rings near the top indicating older Steam Era key. The bit is very turned and off center from the rest of the key. I am not sure if that is on purpose. You can see wear and nicks on the metal as would be expected. Please see pictures for details. Please note that color may vary a small amount because of my lighting. If you have questions please ask and I would be happy to help! -Michelle
