Grove M.F.G B'ham A/A Cap Badges

[ukbrits]

Hi all,
Thought I would bring up the fact about sealed patterns mentioned in K & K for anodised aluminium cap badges.In a recent thread on the Forum, Grove M.F.G B'ham has been mentioned of being in business until 1962 when the liquidators appeared to have been called in.
Looking thro' my badges I have both a Wiltshire Regt and a Parachute Regt made by Grove M.F.G.According to K&K the Wiltshire Regt badge was sealed on the 26th August1964 and the Parachute Regt badge was sealed on the 18th April 1966.Clearly Grove M.F.G must have been producing anodised aluminium badges before these sealed pattern dates (see pics).
I have also seen on E Bay and on this forum, other members Grove M.F.G badges i.e - Northamptonshires,Manchesters and Army Catering Corps 1st pattern, which must have earlier sealed patterned dates than our reference books would have us believe!
Anybody else got some more Grove M.F.G badges or can shed some light on this subject. Your opinions would be appreciated.
Regards.
Colin
