Also, I've never come across a record sheet or even any sort of description of the wepons on a "Morris" varient Preta or a "Cazer" varient Sereph.
SB:W&B is what you're looking for. Record sheets were included at the back of the book. Malak Mi, Preta Kendali, etc.
Per the actual product boxes, and what Iron Wind Metals told me before I ordered them for my store years ago...what I said stands. They are labled as such, & have different weapons configurations than the Infernus variants. Not sure which miniatures you were looking at, but most of these special configurations clearly stand out as different than the Infernus.
Would you care to demonstrate this? It's not what I've seen, and I've handled a lot of those Celestials. The minis themselves match the Infernus loads. In most cases, the differences between the Infernus and pilot-specific load outs are negligible. Give a different coloured glow to a weapon, and it could be a Plasma Rifle, a SNPPC, or a LVSPL, no problem. Got a LPPC? Then that mini shouldn't be using a part that is otherwise consistently used as a HPPC across the Celestials. Unless it's not supposed to be a LPPC. The Preta has just this issue. The Kendali config mounts a LPPC + capacitor. The Infernus mounts a HPPC. Likewise, the Seraph Havalah mounts a LVSPL while its Infernus counterpart mounts a HPPC in the same place (left arm). The significance here is that the Deva Achilleus also mounts LVSPLs (or ERPPCs for the Infernus), which look quite different from what the Havalah got. If you want to say they're pilot-specific loads because of how they're listed, then you've got to explain why there are suddenly inconsistencies in how weapons are portrayed - inconsistencies that somehow just happen to match the Infernus configs.
