You are correct Noel ..It is a Wireless Set No 10

The early versions of GEE and OBOE, which should properly be classified as Aids to Navigation, were mounted in trailers that were available at the time. OBOE in a trailer originally manufactured for the AA radar No 3 Mk 2 is not surprising. What is surprising is that the boys in blue have cornered the market on WW II radar. The army radar personnel and equipment have been marginalised to the point that no one cares about the preservation of the one surviving GL III(c) gunlaying radar, lying neglected out on the Canadian Prairie. It is ironic that the GL III (c) is featured on the FLICKR site of the Quebec Naval museum, but dismissed as a low priority by the RCA Museum.
