This is an absolutely outstanding set of pipes made by Les Cowell for Rudall Carte & Co. in the early 1950's. The company was bought out by Boosey and Hawkes in 1955. This bagpipe is one of only two or three silver & ivory sets made by Cowell for Rudall Carte. It is thought that only about 200 sets of pipes were made before the buyout. 

This bagpipe is exquisite with silver lined tuning chambers and silver hemp stops.  The turning is perfect.  Everything about the bagpipe speaks of quality.
Sadly, I only have small and fractured pictures of the bagpipe above. The silver is stamped "RC & Co" and there is a London Hallmark and 1957 date letter. As Boosey & Hawkes had purchased Rudall Carte in 1957 this seems a bit odd. I'll leave speculation to the reader.
