DESIGN/FONTS: Futura Display and a Question of Weights

[dewline]

Noticing the similarity between the font used in the Canadian Tire logo and the one used for titles and author credits on most of the Star Trek: TOS novels published during the 1980's. I asked around on Facebook, and the conclusion reached by several of my friendlisters there was that we were talking about was called Futura Display. While there's plenty of sources for purchasing licenses for the "main" weight of Futura Display, there's not a whiff of the weight I'm looking for so far.

Any suggestions for legal sources? I've looked at MyFonts and Fontshop, so far.
