There is a Torbjörn skin called Ironclad. It could be prior to the Omnic Crisis, when he was in the ironclad guild (maybe Sven was there too, there is no confirmation)
Titan (that appears in comic) was also made by ironclad guild
New OW2 map is Gothenburg (Sweden), where we can see ironclad factory
and after this there is a shot with new null sector omnic models, it means that this factory belongs to Talon (because null-sector are elite Talon forces)
But who designed all these models? (I already had suggestions about Talon engineers (Talon has own engineers? Or not?))
My guess is Sven. It also could be part of Vishkar work (because revealed OW2 mission started in Rio de Janeiro)
upd:turned out that this building in Gothenburg is Torbjorn’s house
