View-Master I had one in the 1960s courtesy of friends of my dad living in the USA. They sent some really tasty toys over at Christmas. I still have a plastic full size .45 ACP with the case and magazine. Sadly most of the bullets disappeared a long time ago. The Viewmaster was a brown colour and I had the Grand Canyon, the Petrified and a couple of others. Both were around the mid 1960s.
Victory Industries Motorised Boats I still have my Vickers Tractor from that time. They used the base of them to create the Mole and the Firefly in Thunderbirds. It still works but batteries for it are hard to find and a bit of soldering is required to use 3 U2s.
