Original lids have indexing dimples for the wing nut. Repros do not. This guy Andrew knows better. magmustangs is well known to have deceptive descriptions in his ebay ads. Repro base lid and filter sell for 80.00 . Karma will catch up with him hopefully . https://www.ebay.com/itm/154423815045
Thats why I never bought from him there is always a little "something"
@Bob maybe it will help when you always post the correct part as a picture so everybody can learn and see the difference better, thank you.
Dimples are there. Just not as visible with the new chrome filling some of that space.

Andrew chrome doesn't fill in scratches let alone dimples. Maybe your pictures need to be better but chrome does not fill in anything especially those deep dimples. Google how thick chrome is. https://en.wikipedia.org/wiki/Chrome_plating

Here is a example of what the indexing dimples for the wing nut look like on a original.
Here is a link to a vendor selling the repro version. https://www.ecklers.com/double-hump-hipo-air-cleaner-90-94929-1.html
There are some sort of dimples on the one in the eBay auction but they appear to be an attempt to add something not original style at all. And there are more differences if you compare Bob's picture to the one on eBay and the repro in Bob's link.
Obvious repro on eBay.

pretty much the same as on the ram air air cleaner lids for 69 Cj cars(Shelby and shaker cars) ? Gary
Here is another vendor selling a reproduction. It shows dimples but that is not the only identifier of an original lid.

The double hump is a different early design of Hipo lid but the the later Hipo which is the same design as the painted ram air lid has dimples also.
There was a great thread on Forum 1.0 about the details of originals and many pictures. Sadly it's gone. As I recall the contours of the reproductions do not match the originals either.
The dimples are showing on the bottom of the lid...
Not jumping in on the debate of this part but sometimes platers use multiple layers of the copper base (sanded and polished between layers) to fill and hide scratches and rust pits. This method could fill the small detents for the wingnut.

I agree on some platers techniques but you apparently are not aware of how deep the dimples are on a original lid if you implying that they could be covered by random heavy plating. It is hard enough for platers to cover rust pitting in the lids when they are trying to let alone the deep index dimples that there would be no reason to try to cover. I find it difficult to swallow that the chrome plater could typically cover that up without initial body work to the dimple metal first. Of course that begs the question why would you try to cover it up in the first place?

These photos show an original air cleaner top that displays the round clamp marks. They appear around the 'middle hump'. The top photo shows one of the clamp marks where the chrome is worn away on its edge. These are sometimes removed when an air cleaner has been re-chromed. Evidence of these confirms an original lid.
^^
Can someone take those pics and add some arrows to point out the clamp marks?
Maybe I can't see it bc I'm on an old phone. But it is what it is....
And Thnx

Have seen those marks on original 66/67 Hipo lids as well.
Chrome plating is extremely thin and is impossible to fill in anything like deep scratches or especially dimples on an air cleaner. That is why prep is so labor intensive. It isn't like paint where you can keep coating it and then sand and buff.
I think this dimple thing is just an issue that is going to be run into with rechroming.
The people who do the polishing GENERALLY are going to be numb to something like saving that detail or even might tell you that it can't be saved?
IF that detail is very valuable to you then the re-chroming process has just significantly reduced the value of the part but they really aren't visible when the wing nut is installed.
