The first one is definately a P.O.
L. holder for the rear of a British or Canadian carrier, but I don't know about the hinge - the picture isn't good enough to identify the object.
The second one is the top front plate of the engine cover over the radiator as stated in the post by Rob Love and the second piece is identified by the post from Jordan Baker on "Bren Spare Magazine Holder".
Seller claims that he "doesn't know what these items are"....if only he'd been an MLU'er, he'd know all about them.
For those interested....none of these objects fit Australian built carriers.
