Looking for information on these Ira Flagstead model gloves

Hi all,
Newbie to this esteemed forum.
I am an Ira Flagstead (Detroit 1917-1922, BoSox 1923-1929) collector and have acquired a couple model gloves over the years. I would like to see if anyone has any information on these, such as year, scarcity, etc. I am guessing both of them probably date around the mid-late 1920s when Flaggy played for Boston.
First one is a Wilson 651, Ira Flagsted model. I have both a right hander and a left hander.

This glove is from Diamond. Has the Diamond Manufacturing logo in the middle of the palm and says Ira Flagstead on the lower right of the palm.

Thanks in advance for the assistance.
