Back in the day they used this plates to know the weight of the vehicle in tons: https://en.wikipedia.org/wiki/Bridge_plate_(marking)

So I thought it could be a nice touch to add to the car to make it look better.

The model has 2 parts, one that goes behind the grille and the plate. I used 2 screws M1 x 4mm to keep it in place.

I hope you like it!
