Aparently they were dropped off at the job with a bundle of pipe and a swag back with their fittings in swinging from the end, and a bag of hand tools (BG had no insurance for power tools back then).
They all used to meet in the cafe first, the best story at the cafe was of a bloke who was dropped at the job, he rang the doorbell and noone was in, there was a dog barking at him from the other side. He waited a while then thought, I know I'll go back to the cafe, so he thought he would just push his pipe through the letter box and then he would only have the swag bag to carry.
The customer eventually got up or got home or something, only to find the dog impaled on the pipe up against the wall.
He porided himself on being able to do the job with the least tools possible, since that's what he had to do as a walking fitter. I also use my footprint as a hammer and such like. It's quicker to use what you have in yopur hand than to go back to the van for the correct tool. He used to always praise me if I ever used the incorrect tool to get the job done instead of wasting time with trips to the van.
No he hasn't bought an analyser yet, and when I was with him though he had a battery pistol drill it was never used.
I never saw him fail to diagnose and fix a boiler.
