So my Dad quit pipe smoking when I was probably 5 or 6. He purchased this just a little before then. He doesn't remember where he purchased it at or anything else about it. It looks unmarked unless those same semi-circles are the pipe marking, but I don't believe that they are since it uses the same semi-circles on the top of the rim for the design. The case has a generic "Made in Turkey" sticker. It is now in my possession but I wont smoke it. I have it on display. I'm guessing it's not a "valuable" pipe, but as you can imagine I'm very glad to have it.
