I was just looking through Skennerton's book for info on an Sht LE III* upper handguard and saw this picture. Goes to show you that these rifles might seem unsophisticated but to see what an armorer used to look at and use, they suddenly get quite complex. Just my opinion.
" Just remember a 9mm might expand, but a .45 will never shrink"
The manufacturing process for these rifles included many checks of critical dimensions during making. Pieces like the receiver and barrel have several marks denoting passing an inspection after a process, so the stuff on the table there is mostly for machinists to check their work. Only a handfull of tools/ gauges needed by armourers to inspect.
Don't forget that the examiners and especially the Out-Inspectors at the big Base workshops have trays of gauges that they use to certify the finished work. It could be soul destroying when you'd spent hours faffing and faxxing around getting something right. Then it gets to the out-inspector and fails a gauge test for something - so you get it back to correct. Or the same thing and it is sentenced ZF for a low magazine stop face or worn bolt way................
And don't get me going about .300" M1919 Brownings............

A lot of tools and gauges would of been the calibration gauges or tool room gauges, the QC inspector would have had a set for whatever part of the process he was involved in, then the fitter/ turner would have a set of gauges for the part he was involved in.
The pic says it's a display, not a workbench, "some of the gauges applied for the manufacture and inspection of..." From that I assumed it would have been likely most of the gauges used by all of the people involved from casting parts through to test firing...
