Actually, on the measuring front, I did find a problem.
Although I was in engineering all my working career I now have very little in the way of measuring equipment and initially was measuring the various dimensions using the depth facility on a cheap digital vernier bought from Lidl.
I just couldn't get repeatable results even allowing for the fact that this wasn't the best way to do the job so I went back to an old Mitutoyo vernier with manual readings. Instantly the results were much more consistent any variation being what you might expect measuring worn parts in this way.
The Lidl item seems fine used for measuring lengths or diameters using the jaws but the depth rod is both very slender and also not very well supported, especially compared to the Mitutoyo, so I suspect flexing here may have affected the readings.
It's a bit annoying as I've spent a lot of time checking and re-checking the measurements but I guess I should have know better.
