A funny thing guys,
I was looking at that picture of that box of cable staples.
When I first started my time as an electrician, we had an area upstairs at work called "The Museum", most of it had stuff that we only used once in a while, but there was an area, that had stuff that was so out-dated it never got used,
there was boxes and boxes of really old stuff from the 30's, the war years and the 50's.
In amongst this stuff, I swear there was at least two boxes of these same insulated staples, back in the days when electricity was first put into houses over here, you had 2 single conductors, varnished cambric tinned copper wire was used and it was stapled along the timber framing in the house.
So simple, but you didn't need a lot back then, having lights in your house, would have been a heap better than the old gas lamps (if you could get them), it just meant you had more visitors at night, coming to see this new- fangled lighting.
One other thing we had upstairs was an old knife type 2 pole main switch rated at 80A per pole, it looked like something out of a Frankenstein movie, I kick myself for not getting a photo of that.
