I really wish there were as much information on LHS pipes as there is for Kaywoodies. I appreciate your efforts, Dave, in digging this stuff up. I found a Japanese collector who has this same pipe. He says the gold band (I said silver earlier) is 18K gold.
Evidentially, the patent for Bakelite expired around 1927 and some pipe manufacturers such as LHS began using it about that time.
And I do appreciate the offer of doubling my money on it, but I think I'll enjoy having it for at least a little while. =)
Here's the Superfine bulldog I need to work on a bit. The stem is a little under rotated and the finish is a bit faded.
