David, I don't know if anyone asked Guillows for these Mini-Models. it's a kind of grass-roots thing. A number of us have been flying these DC-'root canal' models for several years. Mostly built from scratch using copies of old Guillows kit plans for these models.
There was thread begun in March 2007at the SFA forum where these models were discussed for awhile.

More recently, Howard Littman and fellow Blacksheep Squadron menbers were flying them on the west coast.

A year ago, Howard sent me a PM, giving me a heads-up that Guillows was planning to put them into production. And sure enough, they are finally here.
I guess that Guillows saw something of a market for the 'root-canal' models and decided to join in. If one goes to Hobby Lobby, they can find a wide variety of these 'root-canal' profiles marketed by Lyonaeec and Gayla. They are made of sheet foam, fully decorated in color, and quick to build in a wide range of types and sizes.
At over ten dollars a pop, I don't think that I will be buying any of the Guillows Mini-Models any time soon. I have a good supply of the DC series that I bought off eBay a while back before the prices went out of sight.
