Free reed organs: models 4420, 4430, 4460
Free reed organs are similar to keyed reed organs, but air blows continuously over the reeds (instead of just when a key is pressed). This gives free reed organs a faster attack.
Free reed organs are extremely unique, and are often compared to Hammond tonewheels. They were manufactured during the 1950s and early 1960s.
Wurlitzer models 4420, 4430 and 4460 were among the second generation of Wurlitzer free reed organs, and these models share a lot of technical drawings. Drawings for other models can be found here.
