Thought I would share this in case anyone else is in the same position I was....
I had searched far and wide for an original radio for my '54 3100, but could not locate one. Turning to newer technology, I had problems finding anything that would fit the very narrow dash opening in the 54 / 55 1st Series. Finally stumbled upon one from Vintage Auto Radio. It has the stock appearance, but also has FM and 180 watt power, along with jacks for an I-Pod or MP3. It came with two speakers that aligned with the speaker grille in the dash. I installed it last week, and have to say that I was surprised at the sound quality. I added a pair of small box speakers behind the seat, and I can enjoy the radio even at highway speeds.
The $599 price seemed a bit high, but given the lack of options available, this is a good choice for those who want original appearance with current technology and performance. It's worth a look....
