Add the 3 metal images as layers in the order they appear here.
Select the second metal layer and change its Layer Style to Hard Light. Select the third metal layer and change its Layer Style to Soft Light. Hide the Texport UVs layer and select Layer > Merge Visible (you need to highlight one of the visible layers in order to choose Merge Visible). Unhide the Texport UVs layer and scale up the merged layer so it fit the Casing part of the UVs.(Fig.18)
Duplicate the layer and move it up so it also covers the Rim UVs. Use the Delete brush and delete the part of the copied layer that overlaps the Casing UVs. Merge both layers down. In order to reduce the file size, delete all the unused texture (meaning where it's not overlapping with the Casing and the Rim UVs).(Fig.19)
Press Ctrl + U to enter the Hue/Saturation window. Enable Colorize and change the spinners to 42, 27, -55.( Fig.20)
Again, open the Hue/Saturation window and change the spinners to 0, 16, -10. Don't enable Colorize. (Fig.21)
Create 3 Text layers: "80", "T" and "Z". Move and rotate them to fit the following image. Also, right-click each of the 3 layers and choose Rasterize Type and merge them to 1 layer. (Fig.22)
Hold Ctrl and click the new layer created by the 3 text layers. It will select all information that appears in that layer. (Fig.23)
