here A21 has the mid production type turret balance, so I'm curious... I assume there's a "well known" photograph, or some film, of this vehicle out there, I'm just not sure where. I thumbed through my TD books, but couldn't find it. Maybe the rear of the turret is obscured in the source material? Most 703rd info I come across deals with the M36, as they were the first battalion to make the switch to the 90mm TD (starting in September).
