3025 Heavy Production: FWL vs MW1e

Remember how the Free Worlds League's manufacturing listings only added up to 486 'Mechs per year instead of the 500 claimed in the text? The most popular solution is to add 14 Thunderbolts per year. I eventually came around to that solution too, but now I think it's actually 13 Thunderbolts per year, not 14.

• 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.
