RCEME KC with Screw Threads

[jeep]

Gents. Just acquired this RCEME King's crown badge in silver and gilt in UK (Officers badge? Would be in UK). Two maker marks, 'W.SCULLY' up the horse/mustang back and very faint on the lightning '. . . .LY LTD and underneath . . . . REAL' so I assume SCULLY LTD MONTREAL. Fixings are two screw posts E-W. Is this a recognised fixing for a cap badge, officer or otherwise or is it for some other purpose, belt buckle/pouch/presentation piece etc. Any help/comment appreciated.
