VATSIM Model Matching old liveries

[737_800 434]

Is there anywhere a collection of liveries of former airlines and aircraft? I notice that at VATSIM Pilots fly old airliners or aircraft that are no longer in one airliners fleet. Therefore I would like to see these aircraft insteadt of the standard msfs aircraft. Is there a collection somewhere of those?

Not that I know of. You could download actual liveries for e.g. the PMDG 737 for Continental Airlines and manually enter the path to it into your matching file. They will however be more performance taxing than your common AI model.
