I have 2 old locks that have CM&STPRR printed on them. I also have the key w/ the same print. Both of the locks work. They were my grandfathers. I was curious about any history that might be behind these locks. Where they came from, what they were used for, What years they made these locks, and any type of value they might hold. I know nothing about them so any info would be appreciated. Thanks in advance.
