Rear speakers original or not

Hi all,
Recently acquired a pair of rear parcel shelves, they had a set of, what look like, original speakers in them.
Can anyone tell me if they are the original VW speakers, or an aftermarket set.
They look original to me, with the logo stamp.
Any input appreciated, tia.

The speakers themselves are original as are the nuts used to attach them, look identical to what was removed from the front of my cab.

Couldn't however tell you if they are correct for a tintop or in the correct location but I don't personally think they are but not being a tintop owner I'll await a more confirmed response

The higher end radios of the 80's over here has those types installed in the Parcel Shelf side brackets.

I have a Blaupunkt London radio, which was in the car when purchased, but only speakers in the door pods, these are Pioneer, which may be aftermarket, or retro fitted. The rear shelves did not have anything in them so finding these rears is a result, for me.
