It's one of those odd companies where the name morphed at some point but the aircraft model didn't. I have references to it in numerous books here and for the Skyvan, it is listed as Short Bros. and Harland Ltd. Another variation was Short Bros. (Rochester and Bedford) Ltd though this was prior to aircraft like the Sealand. I reckon that although the official registered name probably was Short Bros. and Harland Ltd, by this time.. the company was better known as Shorts (no apostrophe). I don't think the Skyvan or Skyliner were ever Shorts Skyvan or Shorts Skyliner though which just add's to the mud All reference I have to the actual aircraft are listed as Short S.C.7 Skyvan so blame it on the Irish
edit.. Now I see you bring a 360 into the equation.. A L L C H A N G E!!

Pulling out a copy of Janes (from a much later date) all reference to the Skyvan, 330 and 360 are under Shorts so suck it and see At the time the SC7 was built (ref British Civil Aircraft since 1919 2nd edition 1974) it looks like Short with references to Shorts even though the manufacturers name was Short Bros. and Harland Ltd. My Janes is from 1999 and by that time, they were all Shorts regardless!! :drinkers:
Its a bit like calling the Vickers VC10 the Vickers Aircraft Company VC10... it doesn't happen.
Although the company was Short Brothers & Harlands Ltd after the war, buy the time the Skyvan was in full production (i.e. late 60's), the aircraft company had been separated from The Ship building, although the government continued to have a significant stake in both. The information I have indicates that the use of the name shorts for marketing the aircraft started during the war in an unofficial sense, but became the name used officially in the late 60's, probably arround the time the series 3 with the turboprops was being introduced comercially and the 330 was in the early stages of developement.
