Yep sure is, the Watchamacallit was first produced by Downyonder Corp, the same company that made the thingamajig.
But they went out of business fast since no knew exactly what their products where for, what they did or how to use, the fact that the company kept their consumer friendly mouth closed offering up little to no information really did them in. Bout all know is that both the Watchamacallit and Thingamajig where made of brass.
That is why so many where just thrown out, Tnet is full of them.
