Here is the picture from the actual prop

This is mark 1 or the exact one that potts removes from stark's chest and puts in the display case

I just want to confirm what I am actually seeing or if someone has seen this up close plz correct me

1. The edges of the casing that holds the copper wire is silver
2. Are the edges going down slanted outwards just a little or are the straight???

From what I can see in the picture, I looks like it is slanting a little bit

thnx in advance

i forgot to mention slated outward

The transformer assemblies are silver painted black. The are weathered, allowing the silver undercoat to show through in some places.
