WDC Estate Pipe - William Demuth Company

I have a patient who is a professional eBayer, junk shopper, estate purchaser, and all around picker. He's keep his eyes open for a few pipe favorites for me.

A few months back, I did a big after hours dental favor for him. To pay me back, he gave me this beautiful WDC estate pipe. He just had the bowl, so I had my local tobacconist acquire a new stem for me. I don't know much about the William Demuth Company, but if I am correct, I've dated this pipe back to the 1910's or 1920's.
