You could get a start on this project by searching our forkliftaction website.
You could go to the "Spec Checker"...see the button on left hand side of the home page,,,search the major brands and then you will find photos of a lot of the new model machines......or......probably better to go to the "Business Directory" and search major countries in the category "Manufacturers Index". In this way if the manufacturers have a shopfront, you get links to their websites and can see at a glance the style of their machines. You will note that forklifts made in Italy have the famous Italian design flare.
So start your search for "Italy" in "Manufacturers Index" and then "Germany", then "USA" then "Canada" then Europe" etc
Hope this helps
