This, I think, will be the last of the counters. You should have enough to game almost everything here. For liburnae I would use either pentekonter or bireme counters as these are 'out of date' by the time that liburnae come into use (I think?). Please feel free to copy into MS paint (or similar) and modify anything you like - take or add towers, new colours for allied fleets, completely re-design for use with other rule sets, etc.
