They look like a similar obverse design (with maybe some of the larger outer weak feather detail present on the Noble examples missing on this one) and the chunky campfered block at the hinge end of the pin is similar but the reverse of the wings are different to both the marked Noble examples and the unmarked example with similar Noble hardware in the other thread. As you look at the reverse, note that on the Noble marked wings the top edges of the wing, the area where the wing curves in to join the shield and the top of the shield itself are very thin. On the unmarked wing I have, the reverse outline of the shield is very different. Given the similarities between your wing and the others in the other thread, I'd GUESS your wing is a later example with yet another reverse die involved.
Well, those were my first impressions anyway! Instead of deleting them.....
I just pulled out a pair of AECo wings and I think they are a very good match to the unmarked wings in this thread. Note that the AECo shield design is not quite as tall, a little bit wider/squatter and it has thin vertical lines between the raised flat vertical stripes, whereas the Noble pattern have no thin vertical lines between the raised flat vertical stripes. The shield on this wing is a exceptionally good match to the AECo design. So now I'm guessing this may be an earlier AECo pattern (not necessarily AECo made) wing.
