That stamp font looks to me like an after-market stamp such as is used for house pipes for pipe shops and other outfits. The pipe itself looks somewhat Vauen-like, the reserved design and thick shank.
So my guess would be that this is a house pipe from a Baron pipe shop or Baron organization that sold or gave away pipes, with possible sourcing from Vauen. But I'll watch this thread to see what surfaces. Some members have staggering detailed knowledge on esoteric lore in pipe identification.
That stamp looks similar in type to a Thompson (Cigar) house pipe I have that is merely stamped "Thompson," and "West Germany," which could well be a Vauen. Mine is a freehand with plateau on the brim but not the shank, that came with a p-lip Vulcanite stem that I replaced with an acrylic tortoise shell because the Vulcanite oxidized as fast as I could polish it out.
