Im not bothering too much right now with details as there is very much data to gather. For example, I had hard time to find any info about the C2-S-B1 class, or the N3SA1. After hours of searching, I found through google a post of Elanaiba here on Cerberus topic with a link to a
very cool site full with details and drawings about the merchant fleet. There is a lot of copyright protection pop-up all over, hope is not a problem if I use the data from there.. I see no link about the copyright anywhere in that site, only warnings that copy is now allowed.
Also those drawing would be perfect for the recon manual, but Im sure there is no way to get them for free.
