Just watched this film after many years and I do know that many people have mentioned the use by Colonel Hessler of a Hallicrafters SX28 in his command caravan - nice to see such a pretty Allied receiver being used as a transmitter by a Wermacht tank commander!! However, no-one seems to have ever commented on the fact that both sides appear to use Shure T-17 microphones.
Even more horrendous is the Telly Savalas character driving around in a tank with most of the mantle, turret and gun 'shot away' whilst two R1555 have miraculously survived after having been stolen by the Yank tankers from a passing Lancaster bomber. Actually, I use the term survived in the loosest terms as both receivers appear to have been modified quite comprehesively and here is the photographic record to prove it, enjoy!: -
