Where are the files for the Aqua UI located for OS X 10.4 Tiger?

I am wanting to compile the raw files for UI elements (traffic lights, buttons, scroll bars, text boxes, etc.) for several versions throughout the history of OS X, and I have been able to find the files for Yosemite and Snow Leopard, but I cannot find the files for Tiger. Is there some list of paths for the UI elements of OS X versions that I am not googling precisely enough for? I have tried basically every combination of "os x tiger ui images location".
