Quite a few Enfield barrels were badly damaged at the muzzle by cord wear, I've seen several two groove bores that were worn to an oval at the muzzle.

Now days a damaged muzzle might be counter bored, but that wasn't even thought of back then.
A friend has a cut down No.4 Mk I I hope to trade him out of. He picked it up as a junker with parts missing for 50 bucks. The muzzle end was not onlt corroded inside and out for about three inches, it was bent and flattened on one side and the milled sight ears were bent almost touching the sight blade on one side.
He picked this rifle especially for a jungle carbine clone project because the barrel was unusable unless cut back to carbine length.
The undamaged rear portion of the barrel cleaned up great, the rifle is a fine shooter.

When you see a bubba'ed rifle that is not restorable it can be raw material for a guilt free sporter project of your own, or a JC clone, or a target rifle conversion.

Back in the day spare parts were like hens teeth, if a front sight blade was missing your best bet was a Williams bead. If a military butt stock was broken, you'd come out better getting a Bishop or Fajen semi inletted stock than letting the rifle sit unused for years waiting for a replacement to show up.

A good quality sporter built on a military action often cost more than a good used commercial sporter. People invested that sort of cash because they wanted that particular type of action instead of a generic commercial type.
They picked the wood they wanted, the sights they wanted, and the finish they wanted, rather than whatever happened to be on the rack at the pawn shop.
