House Steiner manufactures the majority of Atlases on Hesperus II, while House Kurita and Davion have smaller plants building it.
Generally a Marik design, however, the FWL exported a lot of weapons to the LC and DC in the 3050s and 3060s to fight the Clans, so they become pretty common there later. Right now, the ones outside Marik space are usually salvaged.
A Liao design initially, but Davion manufactures them while they control Tikonov.
Mostly Liao, though House Kurita uses them too (the -K variant with the PPCs is their design)
Originally a Marik design, but that factory went boom in the Succession Wars and so nobody built any new Centurions until the FS had a plant opened in 3012. Originally it was designed to team up with the Trebuchet, actually.
A Marik design. The plant is on Gibson, though, so once WoB comes a knockin' it kinda becomes theirs.
A signature Lyran machine, like the Zeus or Banshee.
So Kurita, it hurts. Well, the variant with the PPC does. The AC/5 version just kinda stings a bit.
Marik, Steiner, Kurita and Periphery States all build the Hunchback. It's a very common machine and you'll find them just about anywhere.
One of Kurita's three favorite mechs (the others being the Panther and Dragon).
The Liaoest Liao design that ever Liaoed.
Stalkers are one of those "all over" designs. It's built by Steiner and Marik, and it's been exported all over the Sphere. At one point it was the most common Assault Mech in the Inner Sphere.
House Marik has no less than three companies building Trebuchets, and they export them to just about everyone at this point in time.
As far as FRR mechs go, they don't really build their own unique designs right now, but they do have free trade with the DC and LC so they can use mechs from both factions freely.
