BATTLE OF THE BULGE - THAT WW2 FILM WITH ALL YANK TANKS!

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!: -

TOOLMAKERS AT MULLARD & TV BAND III IN 1954

When Band III TV was introduced in Britain early in 1954, Mullard heralded in the new age by having a range of valves available for the new receivers some two weeks after the British Government's TV policy had been confirmed in the House of Commons.

Here, we see Timothy Bustard, a Toolmaker at Mullard's Mitcham factory hand finishing a new anode making tool for the PCF80 triode-pentode valve which acted as a frequency changer for Band III TV transmissions. The tool is used in a press where nickel sheet is fed into the press and seven successive operations of punching cutting and bending using the multi stage tool pictured resulted in a  finished anode being produced.

Here you see Timothy using a strip of nickel sheet as a guide before final fine grinding of the radii within the tool cavities.
