Pair of Enamel Boat Badges

Both badges were found by a diver in the River Thames. One is named to the vessel Madge, dated 1930 and issued by Thames Conservancy, and licensed use on a stretch of water from Sonning to Boveney (nr. Windsor). We are told the Madge was a Thames Steamer and served with the Upper Thames Patrol (aquatic version of the Home Guard! This badge is accompanied by another found in the same area. This is also issued by the Thames Conservancy and while somewhat faded, is marked 62/342 and available until 31st December, 1914. Some chipping to the enamel with some restoration. 4" (10.5 cm)
