This is really great work, you are truly adding something to the hobby here.
I've been trying to reconcile the 3057 and 2750 art for years and these pics really help. At this stage; my headcanon is that I'm figuring a Clan-level refit (inc armour, harjel, LF batteries, ect) basically involved disassembling a warship to a greater or lesser extent and re-assembling the bits; often in new and different arrangements in order to work with the new modifications and additions.
