Well thanks for the guesses chaps. I've actually started to build Beardmore's ugly duckling the W.B.IV

Well done to Joachim and Alan who both correctly identified the model from only it's flying surfaces - great effort
Not much done yet on this one which will be a bit of a background project to turn to when glue's setting or paint is drying on other builds so don't expect too many rapid developments on this, but I'll post occasional pictures as it progresses
For those that weren't aware this one was built to a naval specification and although the prototype performed adequately it eventually lost out to Sopwith's much more conventional looking Cuckoo (So close Nigel)

The pilot's position must have made landings a doddle although the HS engine buried in the middle of the fuselage with a long propshaft running below the legs of the pilot would have made any servicing a complete nightmare. Anyway here's what it looked like before the wingtip floats were discarded
