Floorplate Screws
 

After reading the thread mentioning floor plate screws I tried a search to no avail to a question I have. About what year did Parker Bros. start making the 3 floor plate screws equal in length?

Late teens or early 1920s. That is the closest i can nail it down in my head.


That time period was when a lot of changes were happening in regards to cost savings and ease of manufacturing. And clearly not having to make a special longer screw for the rear of the trigger plate fits into that.
