I know this sounds feddy, but bonus if they're improvised, cos that shits awesome.
One of my favourites is the PRIG - an IRA made grenade launcher that used a packet of biscuits to offset and quieten the backblast.
I also made a crossbow that fired nuts and bolts using wood and resistance bands. Not a weapon of war and would never be lethal, but also probably not very legal where I'm from. I just used it to plink cans in the back garden when I was bored. Was actually quite a scarily powerful and accurate device for how crude it was.
gotta have some love for the warwolf too then surely
Ironclads are dope. Although it's probably not true, in True History of The Kelly Gang, Ned Kelly gets his armour inspiration from seeing blueprints to an Ironclad. Dope ass movie.
yep shits badass Egyptian weapons looked so mythical
The Warwolf (and trebuchets in general) are absolutely dope; but what I love the most about the Basilic cannon is the historical contingency embodied by it. The fate of Eastern Rome was partially decided by sticker shock.
