My thanks to Percy Thrower for helping identify this cap as an other ranks version
I am rather fond of the coloured FS cap, whilst war time examples are fetching good money today, especially for the smaller regiments, the post war examples privately purchased by officers and men are much more affordable, as in the case of this REME Other Ranks example that cost me just £9:As can be expected from a post war cap, the quality is excellent, with the cap made up from red and midnight blue panels, piped in yellow:The buttons on the front are made of staybrite anodised aluminium and feature the regiment’s chained horse badge:The Queen’s crown cap badge also has the chained horse, in front of a lightning bolt and standing on the world:This badge was introduced after the end of the Second World War as King George VI was not overly impressed with the design of the wartime one. The symbolism of the badge design is apparently that the chained horse represents power harnessed, the lightning bolt emphasises the electrical nature of the corps and the globe indicates that its members serve worldwide. The badge was designed by Mr Stephen Gooden, the Royal Academician and was approved by the King on 14th August 1947.
Returning to the cap, the inside is lined with a soft chamois leather headband that absorbs sweat and keeps the cap comfortable:REME’s official dress regulations indicate that the side cap may be worn with No 7 (Warm Weather Barrack Dress), No 13 (Temperate Barrack Dress) and No 14 (Shirt Sleeve Order) dress. As with all of these coloured caps this would have been privately purchased as they have never been issue items, they remain popular as they are smarter than a beret and more practical than a peaked cap.
