First, a Christmas present when I left school to join the RNZAF, 6" engineers square, 6" steel rule, 6" inside, outside spring calipers, and dividers, odd legs. All Moore & Wright. Then when I started my (civil)Aircraft apprenticeship, the firm payed for three socket sets, they are 1/4", 3/8", and 1/2" SAE by S-K Wayne, still going strong after 50years, I'd hate to think of the price of the socket sets today.
