Knickerbocker Silver Co. Backstamp

[lindacomox]

I would like to know what dates the Knickerbocker Silver Co. used for the 2 different backstamps: the capital letter "K" and the Paul Revere one.

I know that the Paul Revere one is more common/prevalent, but was wondering about the "K" one, like was it used before the Paul Revere one, or after. I cannot seem to find an answer anywhere! Thanks in advance.

The Encyclopedia of American Silver Manufacturers by Dorthy T Rainwater & Martin and Colette Fuller Revised 5th Edition notes that the "K" trademark was not used after 1900. Knickerbocker dropped Mfg from their name in 1904 which might also be helpful broadly dating things.
