I got to check that Bicep section out!
I do have a question about the text that I have made red. With the mirror image part, is this a double negative if the preceding bullet point says they are not interchangeable? I could just be reading it wrong. I think the rest of it reads well.
Forearm Armor
Gloss black in color unless noted below. May be painted in accordance with the Color Scheme Guide. If used, all armor pieces must be painted using the Color Scheme Guide.
Proportional to the rest of the costume.
Forearms may be slightly weathered but must be uniform with the rest of the costume.
One on each forearm, they are not interchangeable.
Each forearm is a mirror image of the other.
Forearms have an elongated rectangular appearance with the upper (elbow) end wider than the lower (wrist) end.
There is a raised band around the upper section approximately 1/5th the length of the total forearm.
The rear panel is smooth with no details.
The front panel has an elongated rectangular recess with a piston like detail insert.
The insert is painted metallic black or silver.
The inside panel has an elongated rectangular recess approximately 3/4" to 1 1/5" (20mm to 30mm) wide which starts at the raised band and runs the length of the forearm ending at the wrist.
The front panel has a raised panel detail. The panel has a horizontal rectangle cut out positioned in the upper 1/3rd of the panel and a square cut out positioned in the bottom half similar in appearance to the bicep raised panel.
The raised panel is painted metallic black, matte black, or dark gray.
Both have a horizontal rectangle cut out positioned in the upper 1/3rd of the panel and a square cut out positioned in the bottom half.
