J&R Glen JB10 bagpipes in half chased silver and imitation ivory. Based on Donald MacDonald's bagpipe pattern of 1798 (which was also copied by MacDougal and Thow), J&R Glen pipes were originally made from 1863 to 1911, when the firms of David Glen and J&R Glen were merged. Our J&R Glen pipes are meticulously made to the exact specifications of John and Robert Glen, and perfectly reproduce the mellow Glen tone. J&R Glen bagpipes are now available in our full range of mount combinations, including Full Silver, chased or hand-engraved.
