When I gave a buddy of mine some left-over wall paint I wasn't sure where it would all end. It resulted in the finishing touches for this equipment which he crafted for a recent Swedish post-apocalyptic LARP. It's low-budget and genuinely scavenged, but labour intensive and requiring access to workshop and basic crafts skills:

Do you have any of your own to share? Or perhaps equipment belonging to a friend of yours?
