I am looking for help in determining the date/era of a pair of Spalding baseball cleats. The cleats have an AG Spalding logo with an 1876 Trademark on the inside tongue of the cleats (pic below). I have also attached a few pics of the actual cleats. (My apologies for large size of photos - Im not sure how to make them smaller).

I dont know if it is possible to narrow the date/era of the cleats down or if it could only be stated that they are post-1876?

Also, I have an interest in vintage baseball cleats and catcher's masks; however, I have a difficult time determining the era of the baseball equipment (obviously - reason for thread). Is there any books, magazines, websites, etc., that I could use to eduacate myself on the topic.

Any help would be greatly appreciated! Thanks - Andy
