Thanks for that , Andres.
Another thing to consider with the knurling on the found part is that this suppressor was painted after whatever heat treatment and finish it was originally subjected to. The paint has worn off on the sharp ridges of the knurl, and because it was originally a liquid, it likely produced a small radius on the bottom of the knurl cut which disperses reflected light. For these two reasons, the knurl cuts appear darker and deeper between the exposed ridges. In the unpainted hero part, you can actually see the bottom vertice lines between the sharp ridges, giving the knurl a lighter and therefore shallower appearance.
To illustrate this:
Lighting is everything, folks.
