1920 - 1950 Henderson bagpipes
Admittedly the silver pictures are more revealing than the pictures of the bagpipe, however this gives a pretty good idea of what a premium bagpipe of the era looked like.  The silver is spectacular.
The bagpipe right and below came to me as "1925" but I'm not so sure.  The silver says 1955 but it might have been a retrofit.  No hemp stops.
Hallmarked in Glasgow 1928.
