Finally, done. Very annoying; I had stuff on hold for this, but hopefully this will be there for the next person
Wasp (20 tons)

Lesnovo, Free World’s League
Shadow Hawk (55 tons)

Wolverine (55 tons)

This has me curious: the MUL has all three of these go extinct after the Late Republic era, presumably because Nimakachi of Lesnovo gears up to produce something else when the Blackout hits, but I'm not able to find out what. It's possible they went back to IndustrialMechs, since that's what was originally built there, but I don't know that that's likely, given the wider series of events at the time.
I suppose it's possible they upgraded the lines to standard Battlemechs, at which point the Wasp line is an easy conversion, at the same tonnage and engine rating. The Wolverine, though, uses a different size engine between its standard and primitive versions, and the primitive SHD-1R Shadow Hawk is only 50 tons, so it's even less of a direct conversion of the line.
