Bofors Gun Speaking Tube & Plaque

A most unusual grouping comprising firstly, a copper and brass speaking tube with a section of the original communication pipe. This carries a plaque reading Bofors Guns and Wheelhouse. This is accompanied by a heavy brass plaque which we imagine was fixed to the Bofors Gun and is marked Branch Breaker EWI-13. Both items are in extremely good condition, but sadly we do not know what ship they came from. Speaking tube measures 19.5" (50 cm), and the plaque 6" (15 cm)
