They look strikingly similar, but not identical. Obviously, they're representing the same thing, so that's always going to occur, especially as they are fairly generic shapes. Surely, once the height and widths are the same everything else will be more or less the same on the back of it?
Not to derail the current discussion, but I want to speak to this as a notion in general as I see it posted often when there are arguments regarding recasting.
The general gist of the idea is "if you are both trying to replicate the same thing and you are both good, your items should be very close."
This is a reasonable assumption to make and feels logical on the face of it, but as someone who has spent years with the best possible technology, the best possible reference, and the best possible artists at my disposal, I can tell you that this is an erroneous assumption to make. Even with all of the above at my fingertips, replication is messy and far less precise than one might think.
From afar two replicas may look alike because both are replicating the look of an original, but they won't be the same and in fact, if you are able to compare them using tools like a 3D scanner, you will quickly find just how great those differences are even though to the eye they look strikingly similar.
Obviously, when it comes to turned metal pieces with precise measurements it is MORE probable that pieces will appear closer to one another and have similar measurements, but even then, it is very unlikely for them to be exactly the same or even exceedingly similar. A general inspection may appear that way, but when you get down to measuring each piece, they won't be unless 1) one accurately replicated the other or 2) they worked from similar base information. Don't get me wrong. It is entirely possible that two people will stumble upon an exact measurement without the above two, but extremely unlikely that they would create nearly identical items without one of the two above coming into play.
Also, the idea that measurements will "fall in line" if one or two measurements are known is not accurate. You can do your very best to determine unknown measurements given known, but even then, if you give known measurements to three different people, their findings for the unknown are not likely to be as similar as one might think, even if all three are talented and skilled at finding the unknown.
