If my recollection is correct, the Revell (ex-Matchbox) kit dates back to the late 70's early 80's and at the time represented a civilian Dauphin II. I believe I started one way back then, when it was a new release kit, but lost interest and never completed it.
I would assume that Revell has simply repopped this kit from the original mouldsand not added or modified anything, hence the lack of a winch.
