Not Weird as in 'zombies and werewolves', but super-science ACW is definitely a sub-species of Victorian Science Fiction (VSF); there is a dedicated ACW scenario book for GASLIGHT, and Brigade Games did a supporting figure range for it
Victoria Hawkes, which I think was a character Mrs. Palmer created. Or inspired. Something...
I know they did plenty of ACW related stuff. Mott snack bowls overturned as timberclads, for instance.
Deadlands had the rocket pack blue bellies with kepis, right? Weird war to me.
In Her Magisty's Service had the Gothic War book for VSF creepies.
Sorry, stream-of-consciousness post again...
