Teeters, I've asked this question before but don't recall it being answered:
Why were the RAF's Wessex used on 2 Sqn at Shawbury Mk5's, rather than Mk2's? They were obviously ex RN because if you looked carefully the words "ROYAL NAVY" were still visible under the green top coat. Not to mention the rocket firing control panels on the right hand side, under the pilot's window...
