Is there a reason why they smoke so much? Are the engines just torqued up that much that the oil just blows into the cylinders? Looks like the're running on coal. I think coal would actually be cleaner! Talk about an environmental disaster.
The engine should be Cummind Beige. Tamiya Deck Tan XF55 is a good match.
As far as the no part numbers on the sprues, most of the Round2 reissues don't have numbers on the sprues; or the numbers on the sprues are the old numbers & they don't match the instructions.
Nice Dodges. I really like the CN800. Did you use the L700 frame for that? Speaking of the L700, what happened to your left front wheel?
Also, is that the Italeri base? (I'm just full of questions, aren't I? See, there's another one!)
