In the 60s.& 70s. I saw hundreds of the wee grey "Fergies" sold at the Lanark Market monthly implement sales for export to Ireland

At these sales one could buy most things, from the proverbial needle
to the anchor. I once bought, for the princely sum of £2 {£43new}, an
unused alloy surveyors staff. This purchase pleased my assistant as it was a third of the weight of the Edwardian mahogany and brass
staff provided by our employers.
