The Organina was one of dozens of organette brands made by the Massachusetts Organ Company. This is the Mignonette model, which has 16 notes.
Ads for the Organina stressed the fact that the paper roll was not the valve for the reeds. Instead, the paper holes triggered mechanical tracker arms that operated the valves. It’s also one of the few organettes that offered external roll spools.
