MacRae bagpipes were made in Glasgow from 1897 to 1952. The company was started by Duncan MacRae, who was an innovative man and patented several novel inventions for the bagpipe. The hempless metal tuning slide, the chanter grip, the tunable bass top and a stock with a wooden nut to eliminate the need to tie a hide bag in.
Duncan died in 1930, his son James ran the business until his death in 1951. The business was sold to the firm Grainger and Campbell in 1953-54.
