Size of P53 Enfield side screws

[Ross-shire Buff]

As British Muzzleloaders' Rob Enfirld says in his Facebook video on cleaning Enfield P53/P58 rifles, it's important to ensure one uses the correct size turnscrews to undo the side screws, and barrel band screws.
I could get my PH P53 & measure them, but as I'm quite crippled these days, I thought I might more easily ask members here.

One of my Sons is big into Enfield's. I've heard him say that the original Enfield supplied multi tool fits everything needed. I'll ask him if he knows any actual turn screw sizes.

I have a Parker Hale Sgt's combi tool, which I presumed would fit them all; but have potentially promised myself a Christmas present of some lovely turnscrews.

My Son tells me that the original M1842 tool is the best for that era. He says the reproduction tools are not very good. Hope this helps.
