Allan Stark began employment with J&R Glen in 1914 before leaving for the first world war. He continued with Glen until 1947 when he set up his own shop at 25 Argyle Place, Edinburgh. He and his family immigrated to Australia in 1960 where he continued to teach and pipe. He died in 1963.
I've only ever documented one set of Allan Stark bagpipe and was very impressed with the workmanship.
