I was at the Air Force museum yesterday, and I spotted a detail on the engine bell of the engine on the Titan that wasn't on the engine they had off of the Titan for display, and I can't figure out what it is. It's on both bells, and they are on similar locations on each bell.

In the available diagrams of the LR-87, as well as some photos, there are two "overboard drain lines", likely engine purge lines of some sort. They are uncovered, and located on the outward facing side of the engine, so maybe the Air Force museum chose to represent them with a single raised piece of material, and then turned the engine nozzles the wrong way when they installed them on the exhibit.
