It looks very much like one I had 40 years ago. I had a couple of good aerials hooked up and it dragged in stations like nothing I have owned since.
I was playing around with it one evening and picked up the first broadcast of NZs first pirate radio station, Radio Hauraki, even though I was well out of the theoretical coverage area.
It was a very nice piece and I only let it go because it wasn't practical to take it with us when we moved to Oz. I think I got a dollar for it at auction
