You have a sharp eye, master Laidler
. There was a label stapled at some point on the case, but it got painted over with the grey. Whatever pieces were left in the corners just crumbled away as soon as I touched them
The interior is painted dark green, which must have been the original colour.
Yes, I did think it was for a C No. 7. It is exactly the same as the ones we had eons ago, when I was in the Royal Cdn Air Cadets. I just wasn't sure if the Cdn Forces also used them for the No 4 rifle.
And Roy, given the choice, I just don't understand why anyone doesn't use Robertson screws over the slotted or Philips. They're that superior.

We used to use them but as soon as the screw hit an obstruction the square drive screwdrivers would continue to turn instead of the '....you've come up against something hard here' feel you get with a slot screw, instead of feeling that, the square head 'screwdriver' just continues turning, rounding out the square hole. Problem...........
With a slot, you feel the screw tighten and unscrew and drill a slightly larger pilot hole. With a phillips/cross head you simply reverse it out. With a rounded square head you're what the young Armourrers might call, er......... What's the word I'm looking for again...........?

Because it's not what idea is best, it's who owns it and what are the vested interests the new idea threatens.
Robertson Website - History
Doesn't sound like the idea or the man were welcomed in the UK.
More info here: History of the Robertson Screwdriver
Amazing, but this reminds me a carpenter acquaintance who works a lot in CA told me he rarely sees Robertson screws in the US, and from just looking around for a bit more information I see they're not well known in the UK even today(?)
The usual story: the little guy with the good idea is stonewalled until he either sells his patents to one of the big players or gives up/dies.

They were used here but the only examples I can think of offhand were Land Rover trailer duckboards made by some sub contractor for Sankey Trailers. Good until you needed to unscrew them to replace a broken slat section. Slightest bit of rust in the squared recess and it was impossible to remove them.

They were in wide use at SeaRay boats sport yacht division, Palm Coast, FL when I worked there in the early 1990's.

Ill admit when rusted or full of dirt Square drive screws would be a pain but no worse than a phillips screw, In my experience slotted screws always got mullered up quicker than square drives and in several cases I resorted to drilling a hole into the centre of the screw head and hammering a square drive bit into the top, Slotted screws hate being installed with a battery drill too. The history of Robertson and his screws are quite interesting

Well, what would a Land Rover be without rust after all? I remember lovingly stripping the steel body frames off my SIII 88 and blasting, phosphating and then painting them, preparatory to rivetting them back on again. Nothing like a bit of unplated steel next to rather soft aluminum in a vehicle touted as being "off-road". Perfectly suitable for deserts of course, let us be fair, but otherwise reminding one of a high school science experiment on electrolysis. 
Am doing some concrete forming behind the house at present and it is nice to be able to drive a 3" deck screw one-handed with the screw parallel to the ground. If I had to hold the damn screw with one hand and the impact driver with the other I would be using the nail gun instead.

By coincidence, just been protecting and covering up my wooden garden seats and table and, lo and behold........ It's assembled with those square drive wood screws!. Probably made by the makers of Sankey trailer duck boards!
