This is a pretty small update but I thought it was worth noting as I haven’t seen anyone else positively ID the buttons on Charlie Prince’s jacket.
While I am not 100% sure of the size, the button on Charlie’s jacket appear to be Royal Army Pay Corps (RAPC) buttons which include a lion over a crown over a scroll which reads “Fide et Fiducia” which means “By fidelity and confidence” or ” trust and be trusted” which is seems fittingly ironic.
Anyway, you can find these buttons and knockoffs all over the net, from eBay to reenactment sites to private collectors.
UPDATE: A friend recently pointed out that there are two main variations of this button; a “king’s crown” (1928-1952) version and a “queen’s crown (post-1953) version. Charlie’s jacket has the king’s crown version of the button, which is usually considered a WW2 button.
