1999
There is no time for rest and celebrations in the Civic Weapons factory, below: the town's defence against the Barbarossa calls for maximum productivity! Engineers from the neighbouring Polytechnic School designed ingenious turtle-shaped defence machines, featuring structure beams made in glass-reinforced hard Polyurethane. Thanks God, the raw material to make the glass fibers (by manually breaking dozens of empty wine flasks) is abundantly supplied by the sentinels on the walls. 
The enemy is getting close, we need to speed up the production: to increase it we use a merry-go-round to hold the moulds, so work never stops and we can produce more. (Don't we say - in factory and in town - "We'll work and fight till we've got a beam of light"?)

Once we've made the supporting frame we need to cover it with the protective plates: they're made with the strongest plastics available - using large injection machines made in Augusta Taurinorum - and will protect our soldiers against arrows and thrown rocks. To melt these large parts we need lots of heat, so to warm up the plastification screws we now use imported coal: there's really no limit to the ingenious imagination of Taurinenses mechanicians, right?
