FWIW, the company "Tribble Toys" is actually run by David Gerrold's business partner, Miles Rinis. (I'm not sure how much David actually has to do with the day-to-day operations - probably not a whole lot, though he did contact me a few years ago about doing the website for them. Unfortunately, my employer wasn't interested, and I didn't have the infrastructure to do it independently. Every time I've seen them at a con, Miles has been manning the booth.)
Point being, the toys you get from Tribble Toys are just about as authentic as you're going to get, aside from Lincoln Enterprises.
