I must have some explanations:

Not knowing the speed cameras used in Italy, I needed an example. And actually I took example on one of your images.
The difference between the two is that I redraw it in "svg", unlike yours which is a vectorized "bmp". (Hence the difference in weight).

Now if the fact that I used one of your models disturbs you, I delete ...

The problem is that I redesigned all the images of a "speedcam.zip" for Italy ! So I'll put it in the trash ............ ?
