- The manufacturing chart shows the FWL building only 257 universal designs per year. 13 Thunderbolts would raise that to exactly 270.
- The Earthwerks corporate profile mentions Thunderbolts instead of Phoenix Hawks, and the manufacturing chart lists the Phoenix Hawk at 13 per year.
- When you line the FWL figures up against my figures from the MW1e encounter tables, the Thunderbolt fits perfectly at 13 per year.
From left to right, the Warhammer, Marauder, Archer, Thunderbolt and Rifleman align so perfectly that I have to suspect these values represent their overall, sphere-wide ratios.
