Spurious QO Buffs badge or trial pattern?

[adb63]

Hi. What do you think about this one? Purchased off eBay more as a curiosity than a serious addition to my Home Counties Brigade / Queens collection. It shouldn’t really exist as the regiment only consisted of one regular battalion that wore the Home Counties Brigade badge. The Kent territorial infantry stayed as Buffs and Royal West Kent battalions until the formation of the Queens in 1966.So is this badge a fantasy item or did Gaunt actually produce this badge as a trial piece in the period the regiment was formed and before the Home Counties badge was issued? Interested to hear peoples thoughts on this one.
Regards, Andrew.
