20th century?[]
I'd add an {{incite}} to this, but there's already a general ref to "In a Mirror, Darkly". My quibble/question is this: do we know the Lancer was in use during the MU's 20th century?
Was it stated or just assumed? I guess the latter is pretty solid inductive reasoning: in the 23rd and 24th centuries we saw the MU had similar technology (and people!) to its "normal" counterpart. Still, unless it was stated, how do we know the Lancer wasn't in use during the 1850s or 2050s in the MU?
