Hi Colin,
Going back to my sealed pattern list as supplied by a member here via the National Army Museum I have sealed pattern dates of Royal Artillery, Other Ranks, Queens Cown of 23 Jun 1954.
In the List Of Changes dated November 1951 we have the Glostershire Regiment CB3080.
Note, to have been in the List Of Changes there would have been a sealed pattern created pre this November 1951 date.
As such, both of these could have been manufactured by GROVE pre 1962.
Regards
Chris
