The last issue woodwork for the No5 rifles in the Far East, Malaya etc was all converted No4 rifle production. Handguards can be shortened and the band recess is easily replicated to accept the slightly differently shaped No4 rifle band. Fiore-ends were also No4 production with a small patch inserted into the front opening when cut to No5 length. Butts were similarly modified and the only tell-tale signs were the patch where the lower sling swivel sat and the butt plate wasretained by two sling loop screws from the top and bottom. This was a far better answer to the long screw and bolt used earlier.
If we had to replace rusty handguard rings (VERY common.....) we'd snip the new one with a pair of pliers so as to not loose any length, fit band and braze the nipped ends together. Never failed and an easy fix. Otherwise it was easir to unscrew the barrel than faff about with the flash eliminators.
Been there, done it a thousand times........
