The tanks are newly done, so haven't tried them yet. But I've run GASLIGHT, & played in Skrapwelder's Rampant Colonialism, Colonial Adventures & Valor Steel & Flesh games.
Not sure how to classify the guns on the tanks though. Maybe make the whole unit the equivalent of a heavy machine gun since they're probably heavier caliber than rifles, & will have 6 separate shots.
Haven't thought about to how to manage the wind-up-ness & that once set off, there will be no control of them.
