Falcon Facts: What Does LTD Stand For?

In the ZG Fairlane / P5 LTD page, the first Australian LTD is discussed and I have written that LTD is short for Lincoln Type Design, and not Limited. I found this out in a book. A few people have sent emails because they think LTD stands for something else, so now I’m curious. Three possibilities are:
• Lincoln Type Design
• Lincoln Thunderbird Division
• Lincoln Torino Division

Update LTD stands for Lincoln Type Design! Thanks to Rob McKay, who contacted Ford Australia, and Xmfordfalcon.
