sitigeltfel, it would appear so. You only had to see the Gurkhas with Joanna Lumley to realise that they were impeccably attired, hatted, and regimental ties.
Few years ago I dined with an Air Cdre, ex-OC 12, and another ex-12 officer. Neither recognised my tie.
How many current sqn aircrew wear, or even own, a sqn tie? The last one I bought was in the 60s and I don't recall sqn ties being on offer since then.
That said, we have just been given a sqn tie, don't know which sqn, but it appears to have a Merlin at the bottom. Quite classy but as likely as not to be a company tie.
PS, I also have Bomber Command, 1 Gp and Strike Command ties. Has anyone thought of an Air Command one?
