I was browsing around www.toyrgus.com a few minutes ago, and I found something really nice.

Somehow, someone got their hands on a “1985-1986 Line Extention Binder”. Basically, its a binder full of concept drawings and toy mockups that Kenner wanted to build, but wasn’t able to.

I found one that looks like a really nice concept.
Falcon Cargo Handler
Its called the Millennium Falcon Cargo Hauler. Basically, its a small ship that slides into the forward mandibles of the YT-1300 design. I think its a nice concept, and I wish they could have released it.
