Britmog ..... That's a beauty .... and rare .... they made heaps of the wartime ones but far less of the 'peacetime' models .... what make is it? (Has a slightly Mullard/Ferranti look) ..... during the 80's and early '90s I was a radio tech for the Home Office and we did a fair bit of clandestine equipment for various government agencies .... was the transition time ... in ten years we went from valves to prime-number encryption, SMDs and frequency hopping with the likes of Cougarnet .... steep learning curve for us soldering iron boys

Piece of history .... not to mention your own personal history
