Saturnine Terminator ranged weapons

[Praetor Lex]

Hello. I thought the "lore" subheading would be the best place to ask the following question - I don't play 30K:

 

Why do the gun-arms show the gun hanging from the elbow without the appearance of a forearm anywhere?

Were the brothers who wore Saturnine Terminator plate missing limbs from previous combat, or are the forearms somehow wrapped by the weapon's housing?

 

I like the retro-ridiculous look of the Saturnines, and am aware of their history in the GW's miniature range, but not of any explanation about why the aforementioned gun-arms appear the way they do.  Any fluff explanation for this? Thanks.

As far as I know, there isn’t any current lore explanation. Maybe in the upcoming Forces of Saturn (I think that’s its name?) book we’ll get some more info.

 

For me, missing limbs wouldn’t account for the fact that the terminators can also have fists. I’d say that is is a weight / recoil thing. The weapons are fully integrated into the suits. If you look at some of the Tartaros and Catalhractii heavy weapons, the marine’s hand gripping the weapon is half encased in the weapon’s stock. But not fully meshed into it. I guess this would be the next stage of that approach.

My head-cannon is that the marines arms have nothing to do with the suits arms and are probably folded across their chests within the suit. Everything driven by MIUs or PA to TDA suit integration

Overall it's a very odd design, I think had they said these are advanced mini dreadnoughts I'd be perfectly fine with that. I'd even be happy with the foetus position pilot from the original Contemptor design from Rogue Trader. It looks even more surreal with a bare head. 

 

The ball joints on the hips don't really make much sense to me either because it suggests they have no legs, I'd genuinely love a lore description of how they work.
