RE: 1958 Golde Top Thunderbird
There were the odd British car maker in the Fifties selling sunroofs like Rileys & Wolsleys and Daimlers and the odd Armstrongs these were all Steel tops!.As for the scraped Jag its a 53/54 model MKVII. So did Jag have the mark series before Lincoln!!!!.
Now in the Golde brochure the Jag is a Mark 2 model started production in 61! so this mite tell us the age of the brochure.
