I am going through my Dad's boxes (which I haven't sorted properly since his death years ago) and there are a stash of badges, some of which are a bit of a mystery. This one attached was reputedly a RWY cap badge. Trouble is it has atypical pin type fasteners which I was not expecting, lugs yes pins no. It is too bulky and heavy to be a 'collar dog'. Has my old man misidentified this badge? As to provenance, not a clue, he was a REME armourer and you know they can be real 'pack rats'. Anyway I would be grateful of the assist. Regards Chris.
