Checking out a guy's No. 4 rifle that I'm going to assemble some moderate reloads to deal with varmint threats to his goat pens... So I'm checking that all screws are tight, etc... short story is that some investigation and I see he has the load bearing sleeve/collar that the trigger guard screw passes through to tighten into the body, but I don't see the washer that's part of that assembly.

I can't remember much about that washer before I head for the open stock bins at his local Ace Hardware.  Some questions because my memory is dim from not dissembling my Lee Enfield for a long time.

As shown here between the outside of the bottom metal & the head of the bolt. I.D. should be just big enough to slide on the smooth section of the bolt's shaft & O.D. as close as possible to the head diameter

Thanks guys... will head to Ace tomorrow with the sleeve/collar and the trigger guard screw.  I think one of the schematics found in one pam make it appear like the washer sits between the inner face of the trigger guard and the bottom of the collar.  But I don't spend much time looking at schematics when I could spend the time casting bullets, reloading, out at the range shooting, etc.

I’ve seen that too, and thought it is a drawing error. Other drawings show the washer under the head of the screw where or logically belongs, especially a lock washer.

You might want to check the collar height, if someone had a washer fitted between the collar and trigger guard, they may have filed down the collar. 

I've collected a bunch of schematics about Lee Enfields and Webleys over the years, one reason probably being predicting I might have a question like this and not wanting to start taking my own rifle apart.  Again, if my memory is correct, some of them didn't even show a few of the lesser minor parts like this washer.

I've met a couple of guys that I think get more enjoyment out of buying severely Bubba'd Lee Enfield rifles and restoring them to military condition than they get enjoyment out of actually shooting them.

Seems like an inexpensive hobby when they show you what they bought for $25 - if you don't figure out the bill for what the replacement furniture costs them and other assorted bits and pieces.
