I have an old Bike Radio lying around that I have not used in years. It was just too awkward and annoying and kept getting bashed off the Bike. There are a few bits missing off it like the Lense and a bit of Rubber off a switch. I would say it is about 20 years old. It is quite Clunky about 20cm long or 8 inches by 10cm or 4 inches high by 10cm or 4 inches wide.I have bits and pieces of all sorts to do with bikes in the House mostly Junk .
