Dandelion,
thanks for your help
Yes, it was a Cromwell of the 22nd Armoured Brigade, 5th Royal Tank Regiment. Interestingly, there is a picture of a 'Dingo' from the Divisional Reconnaissance Regiment, the 8th King's Royal Irish Hussars, with the same red,stag head symbol. Were they considered part of the 22nd Brigade rather than the division?
BTW, that's a great website, with lots of detailed info. All this makes me nostalgic for CMBO. Might have to reinstall it!
Thanks again for the info.
