It was a real treat to prepare a Certificate of Authenticity and Opinion of Value for this bagpipe. It's not often that you find a set in this condition with such a respected history. This set was presented to Pipe Major Frank Noble of the Argyll & Sutherland Highlanders, Canada in Holland in 1945. There are some outstanding words and pictures that can be seen here. There are several sites covering the outstanding contributions of the Argyll & Sutherland Highlanders over the years. Simply remarkable!
The silver (hand-chased zoomorphic pattern) is simply stamped "SILVER". I found one other Henderson bagpipe from the same era with identical silver similarly stamped. I have seen other sets of bagpipes from both wars similarly stamped. Not sure why, but it seems to have happened. I'm pretty certain that this set would test out at 92.5 pure silver.
