A sprue of 24 rough and ready Dean Churchward brake handles for HO-scale model railway wagons, such as my Loriot L (G13). Clip them apart from the cage a few at a time, paint them, and glue them on a v-hanger (possibly fashioned from wire or plasticard) on the wagon. I expect they'll occasionally become detached and lost, but 24 should last you a while. If they start selling more often than the Loriot, I'll probably notice and upload a multi-pack.
