Need help with this 20's D&M

Picked this glove up on ebay the other day...Cleaned up real nice...We were wondering if anyone might be able to help us out with it...Looks very similar quality and looks wise to the Walter Johnson gloves on JD's site...The weird thing is there is a block letter J near the heal and we could find no listings in the source books with any D&M having a J in the model number...Any thoughts???
