I have seen these rank slides on many occasions and have heard differing views on them. Some people have even claimed that these were never worn.
Here is another from attached Signals (264 or 63 Sqn). I have seen these with 'Royal Signals' spelled out or the 'Royal' part abbreviated to 'R.', as below.
The following Ebayer seller seems to have many - Sigs, AGC, RAMC etc. What are members views on these slides?
