NFS district 21 (Sketty) raw edge BMB 1941
Not sure on the rank but commandant/senior officer I think, it appears to have had rank star at one stage which is now missing and two blue bands of differing thickness which hopefully someone will know what exact rank they are for.
I did not have a BMB raw edge in my collection or a Welsh NFS lid so two birds with one stone so to speak.
