When I detailed and painted the last batch of GS-4's I made up several detail parts for up grading the GS-4 to the post 1945 rebuild version. One photo shows the drop hand rail posts and the brass ball ends that are needed for the handrails. The model was originally delivered from Overland with just plain wire for the handrails. The other photo shows the hollow marker lights. I made somewhere around 15 different parts for the GS-4's. If your an SP modeler and interested contact me off list.
