A deadstock British khaki twill boiler suit, probably from the 40s or 50s. Maybe earlier, maybe later. Classic military style ring-backed resin buttons, and standard military style fly buttons. A very strange internal rear cinch belt with “British Make” prong buckle. It was made by Practical Uniforms of London SW12 … Fantastic! Far too big for me, sadly. The Wabash Stripe pocketbags are a nice touch, IMO, along with the fancy decorative stitching at the pocket openings.
