It seems there is pretty good evidence that Stern made pre war pipes for BBB. We hope to flush that out here as more information becomes available. Please feel free to add any information you have here, or send it to firstname.lastname@example.org. Perhaps we can eventually add the result into the main article... --sethile (talk) 09:37, 3 June 2016 (EDT)
The case for some Pre-war BBBs having been made by LHS
From a thread on PipesMagazine.com by Dave Gossett:
Here is a BBB that was possibly made by LHS. I hope the BBB collectors chime in with any information. There are too many similarities to just be coincidence. Besides the fact that LHS pipes are great burners, the scarce information and mystery surrounding L&H Stern piques my curiosity of this extinct American pipe maker.
Besides having the look and feel of an LHS, It is stamped Superfine, also the name of an LHS model. It has a stinger identical to LHS pipes of this era. They both have the two piece aluminum fittings in the stem/shank connection. The stem has a pale blue dot surrounded by a silver circle, the same as an LHS Warwick. The model number stamping is the same font used on LHS from the 1920's through the 1940's.

Ludwig Stern moved his pipe factory to Brooklyn,NY in 1920. Louis Blumfeld opens an American branch in New York around 1914 according to Pipedia. These two pipe makers were practically neighbors in the 1920's.
Editors Note: You be the judge and form your own conclusions, but it is compelling evidence, to be sure!
