Vintage 1950s Garringtons "Red Diamond" adjustable spanner, marked 12 inches in length.  In good overall condition for age, as per photos, with some minor tarnishing but little sign of wear around the head. Features a ring spanner of marked size 7/16W in the handle. Good quality classic tool, stamped "Made in Britain", smaller versions of which were routinely included in toolkits of Jaguar amongst other prestige car marques. 

Found when clearing out an old garage for a family member, one of a number of vintage tool items I am currently listing.
