The Ghost Bears still produce Executioners and possibly Mad Dogs if I'm not mistaken. They don't have the Viper anymore, not sure if they still do the Firemoth.
The Warhawk has never been produced in the Sphere.
The Falcons were able to produce Summoners, Kit Foxes, Novas, and Hellbringers, although they may have since switched to later designs.
I feel like someone was producing the Stormcrow, at least for a while. The Ravens, maybe? They might also have been able to do the Mad Dog.
The Wolves were kinda SoL for a while, having pretty much no factory capabilities whatsoever. During the Jihad they were cobbling together Gargoyles from spare parts. They've since started making Timber Wolves by hand.
As far as we know, no one is currently making the Adder, the Ice Ferret, the Mist Lynx or the Dire Wolf.
Of course, all of this is subject to change by Dark Age. Did I miss anything?
