Rope, cord and cable making is an interesting subject. If those cords are not silk, and I assume they're not, this must have been quite soon after the introduction of synthetic fibres. IIRC the patents and rights for a number of British-engineered fibres (including Nylon?) were among the items demanded and handed over in exchange for Lend Lease. That was after the reserves of gold, silver, stocks etc. had been exhausted!
Do we really have people around who think such things should not be shown for some reason?
