This RX was first introduced in the late 1960s and was the first transistorised communications RX. It sold for £48 when it first appeared, and we all (well quite a few of us) wanted one.
By modern standards it was hopeless. At high HF the image rejection was pathetic because of the low IF. They still appear on sites like eBay for a fortune. They have become collector's pieces. I briefly owned one a long time ago, goodness knows why. They used germanium transistors and these became leaky with time. Many need replacing. Mechanically, these receivers were excellent. Shame about the electronics!

I've got an Eddystone 990R transistorised VHF communications receiver from 1967.Still works quite well, useful for tuning across 30-40 MHz to see what activity there is. Mostly germanium transistors I think but, so far OK!
