This mouthpiece looks a lot like a vintage Conn Steel-Lay or a Naujoks-McLaughlin with a different name on it.  Store branding was as common in this era as it is today and this was likely made for Henton?

It has a short shank and metal table rails and tip fused onto the rubber.  There is a large chip at the tip of the mouthpiece so it will need a fairly large amount of work to play.
