CSA Auxiliaries

[Guinness]

Rather than continue to junk up other people's threads up with my boring Auxiliaries, here's the whole family of CSA Auxiliaries, including an Amphibious Transport, Destroyer Tender, Freighter, and Oiler. All 4 are built up on the same basic hull, with variations in upperworks, and in the case of the Amphibious Transport, more powerful machinery.
