With the utmost respect the Mr. Laidler who I have traded a few emails with and what smellie and finlog have said above, you should also remember this.
You have the right way, the wrong way and the Army way of doing things, if you read the 1931 Instructions for Armoures, read what Mr. Laidler tells you and then read the 1991 Canadian No.4 maintenance manual you will see differences. So remember the Canadian No.4 manual is written in such a way to keep an old war horse in service.
As an example if a fore stock had over .010 wood crush below the receiver and trigger guard the fore stock was to be replaced by British military standards.
If you look at the Canadian manual and read between the lines you will see a section about bent trigger guards and adjusting trigger pull. There are no more replacement fore stocks so the Canadian manuals states the Canadian armourer "MAY" have to straighten the trigger guards that were bent in the field to adjust trigger pull.
If their are no replacement fore stocks and the existing fore stock has too much wood crush the trigger guard will remain bent rather than taking an Enfield out of service.
Bottom line, read what Mr. Laidler has to say and apply it to the condition of your old war horse and remember there are more than one way of doing things. You are not going to throw away a fore stock as the British did and you are going to make do with what you have.
Wood crush can change the angle of the trigger guard to the point that it is impossible to adjust the lobes on the trigger for proper trigger pull. Below the word "MAY" means the trigger guard can also remain "bent" for proper trigger pull...................
"the right way, the wrong way and the Army way".... and what you "may" have to do to keep shooting your "old" war horse.
Read the Enfield manuals in Badgers online library and also read between the lines. Below, bending a trigger guard would be a Cardinal sin for a British Armourer, BUT you Canadians are still using the No.4 Enfield rifle, and "still" keeping them in service.
