Has anyone seen a pipe like this I've never seen a patent no on a WDC pipe

 

[Richard Burley]

Not I. How do you know it's a WDC? Is there other nomenclature?

Fine looking burner. Enjoy it in rude good health. (Old Kirk saying).

Yep! I have seen quite a few with Pat. Numbers on them. I have a two early Billiards one with a silver rim cap and the other with the Dunhill like inner tube that have them.
William Demuth Co. holds quite a few patents if your search for them. I have quite a few copies of them but, there in PDF form and am unsure how to post them here.
