Trigger-guard: Bent and/or TWISTED?

Stock Collar (the steel tube between the trigger-guard and the body): Not the correct length?

There was an official gauge and tool for evaluating and adjusting these collars; now virtually unobtainable and probably quite expensive, assuming someone knows what they have.

Originally, the collar was adjusted to the fitted fore-end, thus it is NOT an interference fit in the wood of the fore-end. The collar is there for VERTICAL stability, not lateral.

All this fitting, gauging, adjusting, rinse and repeat, was hugely expensive in skilled labour; done properly, it produced a superb end result, but was a bit of a worry when your system suddenly needed several hundred thousand rifles to make up for last months combat losses (see the butcher's bill for 1916 alone) and expanded recruit intake.

Peter Laidlericon has hereabouts posted some detailed instructions on the finer points of getting these rifles RIGHT. Find them, print them, read and annotate / highlight as desired, then follow them in detail. Worth more than their weight in unobtainium!
