LG follower Melanie Morrison sent in this fabulous snap of a team of Glasgow slaters, taken on January 22, 1934.
The picture, found amongst her late grandmother's possession, features Melanie's great-grandfather with his pals and colleagues.
Working high above the city, and out in all weathers, with tackety boots their only concession to safety gear, these men helped put a lid on the city's homes and businesses.
Armed with their slaters' hammers, and a slaters' stake or a bench iron, they cut and fitted the best that Ballachulish or the 'Slate Islands' of Seil, Easdale, Luing, Lunga, Shuna, Torsa and Belnahua had to offer to keep Glasgow wind and watertight.
It's unusual to see a picture of working men from this period all bare-headed. I suspect the gaffer must have given the order: 'Bunnets aff fur the fotie'.
Melanie wonders if anyone recognises the company name.
* LG fan Audrey Wyper has come to our rescue, scouring the 1935 Post Office directory to find P. White And Co. Slaters listed at 10, 26 Paul Street, off Cathedral Street.
