The links aren't working for me either - could be because I linked them while I was logged on EBay.
They are items:
6571139831 Bren Gun Carrier Blackout Headlamp pinhole
6571141652 Bren Gun Carrier Black out Headlamp with slit
same seller, same high bidder at three bids, as of this minute
And this guy has just listed a bunch of carrier parts, too:

This all may be old news, or en famille for the carrier crowd, of course.
The third item was thisL 6570444304 - 2 Gallon "Flimsy" Canadian issue 1944 dated WATER mk
