I have been trying to figure out the connection between L.W.K. and anything. L.W.K. is the airport initals for Lerwick in the Shetland islands. This wouldn't made much of anything around the time this pipe was made in the early 20th century. But I have seen some references that BBB pipes were held in high regard in Denmark around that time. Lerwick being one of the northern most ports of England at that point. It might make sense to name a line of pipes after a port that had some common history with Scandinavia. The shetlands being originally settled by vikings.
