There's a youtuber with the name "Aristocob" (Scott) he owns a store that only sells corn cob pipes and he may know a great deal about the older ones. His store website is aristocob.com, which has his direct email address. You may want to send him a message, I'm sure he would be interested in helping you or put you into contact with someone who does. Also you could try emailing the company who made it and see if they are willing to date it for you. They may look at the pic for free if your lucky.
