Thank you!! I believe it is a Pioneer but not positive. I purchased it used but unsmoked on ebay quite a few years ago. I believe the listing said Pioneer brand as well and I have seen other Pioneers online and they look the very same; with a briar shank piece with simply "Austria" carved on it. And it is a true gourd not made from wood like many today.
The pipe is beautiful, there is something about a real gourd calabash.
Wooden calabashes just aren't the same thing.
I've got two myself, one is a Bauer bought in Denmark 1994.
