Paul Martin looks back through the archives at some of the best antiques and collectables discovered across the UK. This edition from Dyrham Park in Gloucestershire features some of the best musical items. A signed sheet of Glenn Miller music beats expert Adam's Partridges' estimate in Loughborough, and a concertina is the star of the show in Sunderland. Plus, Paul explores the history of one of the oldest brass bands in the world in Derbyshire.
