capandball on YouTube, sells kits for making various paper cartridges and boxes to hold them, along with other stuff. His videos are well worth watching too. He’s a Hungarian Military History teacher (professor?) and competes in international ML matches. Hunts with originals and replicas too.
His video on a pair of original wheellock pistols is amazing. I never knew how fast those locks could be.
