The tank is probably quite anachronistic.
Having very little knowledge about the billion different sherman variations. I bought this one for my market garden project. It’s called “the British Sherman” so a assumed it would be used by the British.
Little did i know guards armored division had only Sherman V and Vc and mabye a tiny number of Ic.
You can justify a Sherman III in Market Garden by saying it belongs to 8th Armoured Brigade, in support of 43rd Wessex.
All the best,
