Hello Titanseers, thanks for dropping by. When I purchased Warlord No.10, Ex-Noctia, unfortunately the Belicosa Volcano cannons were missing but after some detective work from the Princeps at Titan Owners Club, we managed to track them down with the new owner of a Reaver Titan also sold at the same time. A lovely chap, we managed to get them sent back to me and finally after his house move and me absent at sea with work - I was re-united with them and got to work making them fit Legio Astorum livery and the other Astorum Warlords of the Emperor's Halo Maniple so they can be interchangeable.

Here you can see the Astorum decals so far, I'm utilising the Atarus decal with the laurel and the Titanicus "T", but the Forge World symbol was swapped out for a Lucius one (was possibly Forge World Phaeton or their new fledgling Forge World of Atar-Median).
Here they were in the original Atarus scheme, it's a shame I had to overpaint the Atarus decals, but I preserved one panel and a red stripe or two similar to Ex-Noctia to honour the previous livery and machine spirit! I will add magnets to the joints so I can swap between titans too.

Cheers, Siph
