Here is a photo of my red, white and blue Trip-L-Top.
The US patent is number 2,619,769 and was awarded on December 2, 1952, to Donald L. Gallaher from Seattle, Washington (filed May 18, 1948). I believe it corresponds to this top because the internal shape follows closely the drawings and the card with the directions lists the company as Plastal Specialties of Seattle. However, there are many other patents for multiple nested tops. For example, 3,201,896, awarded on August 24,1965, looks very similar. Or much earlier, like 1,858,639 from July 6, 1931, also for a nested 3+ peg top.
Now, I have a copy of a toy trade magazine ad from 1950 for my favorite triple top, the Rocketop from Anderson Die Casting and Engineering. So, go figure . . .
Here is the Trip-L-Top spinning:
PS: I have an extra instructions card, torn in two pieces but complete. IF (and only if) you already have the top (or win this auction) you can have it.
