I am reliably informed that there is a Wigmore Castle in Herefordshire. This also fits with the 63 AoS, 1st Battalion Herefordshire Regiment.
I just need to confirm "Accussor" or "Accoustic" on the front of a Cromwell T187676. The name is to the right of the MG and there is a C Sqn symbol to the left.
Cheers
