 Some enthusiasts define the age parameters of vintage or classic gear as “old enough to exhibit the glow of vacuum tubes”, but the designation may include some early solid state gear.Some even sub-specialize in military radio collecting and undertake to restore and operate surplus communications equipment, much of it dating back to World War II, from AN/ARC-5 command sets and US Signal Corps SCR-300 and SCR-536 walkie talkies to exotic gear like the British Paraset, a small espionage transceiver supplied to Resistance forces in France, Belgium and the Netherlands.There is considerable interest in vintage military and commercial radio equipment among EU amateur radio operators, especially gear from British manufacturers such as Marconi, Racal, Eddystone, Pye, and a variety of Russian, German, Canadian, British RAF and British Army equipment, such as the well known Wireless Set No.
