A really nice piece of British workwear from the 1920s-50s … hard to date these exactly. I bought 2 of these deadstock waistcoats a few years ago. They were made by Milns, Cartwright and Reynolds, Ltd. EMCIAR Brand. MCR were Livery Tailors in London, according to mid-1940s editions of The London Gazette. Surprisingly for workwear, these are exceptionally well made, without any of the sloppy tailoring you so often find.
The front of the waistcoat is made of very heavy brown corduroy and it closes with 6 buttons of standard workwear brown plastic type. There are 3 large, flapped pockets to the front. The lining is made of linen, and is stamped City of Westminster, so presumably these were for Westminster Council employees. The back and arms are made of heavy twill cotton – almost a moleskin finish but not quite. I haven’t come across many better examples of these.
