Well, I remember seeing some Scientific kits now, but haven't even thought of them in decades. How long has that company been out of business? I'm thinking it was back in the 1970s, because I don't even recall seeing one available after 1978, if not before that. I saw the boxes, but I never purchased one. I think that may have been because of the price, but I'm not sure. I do know that I had limited means during my childhood, so that's probably most likely it. Is anybody making the kits now? If so, who?
