I think we have hijacked this thread - hope no one minds. Tekno and Vilmer are my passions, so I can go on forever!
As shown in Tick's ebay link, that is a Vilmer Chevrolet. But Noble is also right in that the largest one on the left (a Tekno) is closer to a Chevy truck prototype than a Dodge. Some of the following are my assumptions - no historical record has been found so far!
Lego or perhaps another Danish toy producer made a Chevy truck in 1/43 or 1/50 scale in many variations. Yes, that Lego - all in plastic. Their ads called it a Chevy. Then Tekno and at least one other Danish toy company made their own variation in metal. These were generic and never advertised as Chevy (or Dodge), perhaps to avoid being sued. They looked a little like their smaller Dodge trucks; hence, collectors call them Dodge!
Clear as mud?
