Used OEM Suzuki 1973-77 GT380 Left Side Cover 47211-34100-737 Stardust Silver
Suzuki part #s have two groups of five digits separated by a hyphen and if it is a painted part another hyphen followed by three digits. These three digits are the code for color.
Suzuki often used the same color with different names and three digit codes so it is very difficult to be exact when determining the color. To make matters even more confusing these color names and numbers were only for the North American market and may be something different in Europe and Asia.
Bottom line is there is no way to be certain that this will match your tank or opposite side cover.
I believe this is -737 Stardust Silver as the label inside indicates.
This might be a new part but can't be sure so selling as used. There are no signs of this ever having a side cover emblem or that it has ever been mounted but it does have decal and they don't normally ship new ones with this decal.It also has a Cycle products label inside (photos 2 & 3) like a new one. It does have scratches to the OEM paint as shown in photo 1.
