As I usually do, I put a model next to me and try to make it. This time a rusty & dusty iron made me company for several hours. It is made in real world dimension, at about 21 cm length.The material of metal part ( rust ) is procedural. The wood parts instead is a texture. I made also 3 masks for the dust.Everything is included in the file (Textures & HDRI).Rendered in Blender 2.92 (cycles). All the parts of the model and the textures are well named & organised.
