I would rely on the existing official resources, no matter how little there is. Take MS-09F Desert Dowas and MS-07F Gouf Hunter for example, the FMS (Fukuchi Mobilesuit Station) articles by Hiroshi Fukuchi were and still are the only official sources for FMS design series, as many Japanese fan blogs do not site official references to back their information.
I will take a good look at the link and infos you gave me and see what I can help. Cheers!
Thanks! I think from now on I'm going to leave the obscure mech material alone unless I get lucky, and find the official translation for it somewhere (.org sites or others), I'll stick with what I can do that is within my abilities.
I'll keep any unofficial site information as my personal notes in case somebody wants to compare.
