Description
Found this in a library clearance in Heybridge, Maldon – didn’t know much about it, just saw the service light was on. It’s a bit of a curiosity, honestly. Came from a Soho central London collection, but I’ve moved it to Heybridge now. If you’ve seen one like this before, I’d love to hear what it does. Thought I’d share it in case anyone’s into retro tech or just curious. Price is £27 if you’re interested – no pressure, just passing it along.Seller Information
