Who made the Golden T special 300 toy wagon?

No way to find out yet. I've been searching. I have acquired a Golden T deluxe 600 wagon at a yard sale. I pretty sure it is from the early 1960's. It was distinctive for having yellow graphics instead of white and a yellow handle/pull. My best guess is that I have the largest one made. Ultimately, for items which are less popular or are not tracked (as bicycles are), these pull wagons are worth only what someone is willing to pay for them. Before the economy crashed, I think mine would list for $90 and sell for maybe $60. I think today it would sell for no more than. $45.
