I am making a fleet of Matchbox scale cars and need weapons.
More: The Road Warrior/fury road style improvised crossbows, bolt-throwers, zip-guns etc.
Less: Hi-Tech, manufactured-ammo consuming machine guns, rocket launchers etc.
There are loads of options for WW2 and Sci-Fi fire arms, but I can't find a good source of post-apoc meets medieval technology. GW has some interesting bits, but Warhammer Fantasy stuff is going through the roof. In my imagination the chain guns and .50 cals ran out of ammo ages ago...
Any suggestions? Scratch-building tips?
