Hello Carlos, you made the most out of these hard to make models. The ACE Tartra and the MAC steyer are hard ones to make into convincing models and you did it ! Nice little dio's too
For the Tartra I realy like the new top, much nicer than the original one I used.
You may consider touching up the radiator very little with black to give impression of slats.
Here is my Tartra T 57 for comparison and its easy to see your top is much more resembeling the real thing !
Keep up the good work, Alfred
