Gents, Three badges have come into my possession that I believe are Royal Signals, that I would like to identify if possible. Unfortunately I can't post pictures at the moment so can only describe them: All three have crossed signal flags- Blue on left, white/blue on right. One has one pip/star between the cross of the two flags at the top, second has two pips/stars, one above, one below the crossed flags. The third has a Queens Crown above the crossed flags. All three are I guess from Mess Dress as they are made of gold wire ,on dark green cloth backgrounds and about two inches high top to bottom (not including the background patch). I'd be grateful for any info on them, i.e what they signify, age, are they still current? etc... I've tried looking on google images, military tailors sites etc.. but have found nothing other than the normal crossed flags. Many thanks..
