I don't have a period correct radio, but it is a Triumph radio (it says "Triumph" on the face plate), which I installed in a TR radio frame. Instead of a single speaker I have three. One facing the driver, one facing the driver footwell and one facing the passenger footwell. All speakers are mounted in the radio frame and NOT mounted in the door panels, or in the rear seats or anything like that. The radio was $100 from E-Bay; the Radio Chassis was an aftermarket item for about $100 from the UK and consists of three steel panels that hold the radio and single speaker facing the driver as original, however, I had it modified to fit three speakers, speakers were $20 each. The radio is powered but does not power the speakers - in other words, when I turn the radio on, it lights up. However, all of the speakers are connected to a wireless Bluetooth 200W stereo amplifier (The Nobsound NS-20G 200W Mini Bluetooth 5.0 Power Amplifier - $55). This is hidden in my glove-box, however it's small and discreet so you can mount it anywhere. I Bluetooth my smart phone into the device and it delivers the amplified signal to all three speakers; it sounds great even at speed. If anyone is interested I have a classic UK Grundig AM/FM radio that would also be great as well and I believe was one of the radio options in the 60's $200 if you're interested - pm me at
