Matt,
Glad you liked it. This is the same pix I sent you off line awhile back. While most large diecast are 1/18, the Mira / Solido line has a few 1/19 items, which look ok with 1/20. Mira / Solido also have a series of 34 / 35 Ford cars and pickups, and several late 40's pickups that are also 1/19, plus several versions of this GM truck platform.
Sadly, these models are normally listed / sold as 1/18 and marked 1/18 on the boxes! But if you read the markings on the bottom of the models, they clearly say 1/19. I've also double-checked the general dimensions in scale, and it's very close. These models would also look good with the Euro style SM32 - 1/19 trains.
FYI, Mattel also has a few 1/20 vehicles, a Ford TT commercial van, a series of 40 Ford panels and a late 50's GMC commerical panel. But you have to look HARD to find them and the scale isn't on the box.
Later, Gary
