This could well be due to the gold cap delaminating slightly. The bond on the inside of the lugs is the weakest on a gold cap and they have been known to "peel" ever so slightly, reducing the lug width. You will need a powerful loupe to see it, but it is probably the cause.
So, I don’t have a powerful loupe, but the one I have plus a regular iPhone zoom was already enough to produce this:
Let’s ignore the WM mark on the lug, but looking at the gold-cap on the inside of it, as you mentioned, it’s clearly not closely attached to the steel core anymore but a little “bubble”. The contrast to the outside of the lug shows nicely - I think you’re spot on! Thanks a lot! 😀
Considering that I made it up on the spot to make you faff about with your loupe, I call that a result 😁😁😁
Did you measure the old end links you took off? Are they narrower than you other set?
