Whats the scoop on lightened bolt handles?
This might be a myth busting question but enquiring minds have to know...
I continually see sellers comments that jungle carbines had their bolt handles drilled out to reduce weight, the trouble is I see drilled out bolt handles on all kinds of no4 enfields, and including one here with an A suffix, which would indicate that at least early in the war they were already drilled out then, for what reason I don't know.
Is a drilled out handle a sign of a genuine no 5 bolt when on a jungle carbine and would that then mean that a non drilled is not correct equipment?
Does that mean that the drilled out handles on no4's we see around today were just a random installation from some bolt maker who was making them with the hole, or are they retrofitted from later carbine production?

BSA used hollowed bolt knobs on all their rifles, not just the No. 5s. That is why so many No. 4s have them.

RJW, There are three words that are never used in the L-E world...exclusively, never and always.
There are two sizes of drilled bolt knobs, BSA looks to have used the smaller hole for it's entire production of No.4s. While the larger hole appears a No.5 item, it may not be in practice. No.5s are also supposed to have a waisted butt stock bolt, but both of my Fazakerleys have standard No.4 butt stock bolts.

PS I checked my notes and reference material to see if the drilled bolt knob was part of the original pattern, but I have nothing anyone else?

I have a 1941 Long Branch No.4 Mk.1, and there is a hole in the correctly stamped Long Branch bolt handle knob, just like the example you have in the Knowledge Library here.

Oddly enough, my "3L" w/ the apparently original bolt (markings correct and S/N font matches, etc.), has no hole in the bolt knob....
- at least- well, I saw it before I left the house at o'dark thirty to cut on a certain barrel for a certain project, ...subject to verification and correction!

I think you'll find that on BSA production, the hole in the bolt was an indexing locator, presumably for some machining operation - I would imagine to do with the short and long cam groove. BSA, being a private contractor, were prety well left to their own devices and as such were free to make the best use of their material and resources subject to conditions of course........ A certain Reginald Shepherd got BSA the complete No4 rifle contract (they were originally just going to make the woodwork and barrels) following on from their success in doing the same for the Bren Gun but Mr Shepherd convinced the Inspectorate of Armaments that they could slow down No1 rifle production without a break and gear up to make the No4 as a whole item. So they did.
Mr Shepherd............., you all know him.......... the man who authorised Harold Turpin to spend a maximum of £5 and take 10 days 'absence' to make a prototype SMG. That's him S for Shepherd, T for Turpin and EN for England. The STEN gun co inventor
The bolts were all fully interchangeable and in Malaya, we didn't differentiate between them at all.
Some of the No5's did have a large hole in the bolt handle, some, BSA's had a normal BSA type No4 indexing hole while others, presumable from the Fazakerley stable had just a round knob. There didn't seem to be a set pattern to go on. The part numbers were the same (?) and, as I said, we saw and used many, many hundreds

I think a third of my No4 rifles have a hollow bolt handles, they are a smaller diameter holes than my No5's. I don't have enough rifles to draw a conclusion, just an observation.

Long Branch seems to have drilled out until the MkI* modification was introduced. Maltby seems to never have, likewise Savage.
Some No5's have a larger than normal hole about 1/2" that actually required(?) the knob to be shortened about 3/16" I believe.
Perhaps as No5 production continued after No4 production was reduced or halted at war's end, there was a relaxation of standards to allow No4 bolts already on hand to be used up?

Surpmil, My '41 Maltby has a drilled bolt knob. There was/is some speculation that one of Maltby's start-up issues was with the bolt manufacturing and BSA bolts may've been utilized to supplement production. I have yet to see an original '41 Fazakerley, maybe, maybe not.

I had a Maltby in the first 2000 made and have seen photos of a couple of others in the first 2-4000 (SN's in the 10,000 to 14,000 range) All of them had solid knobs with just a flat and IRRC all the bolts looked original. Does yours have the Maltby "M" anywhere on it? Mine did.
