Nathan M5 Parts

Dennis McCurry offers the following description of the parts of this old, round base M5:

Starting at the bottom you have 5 back caps or end caps, above that the diaphragm heads or simply heads, above that the diaphragm assemblies (attached to the front of which are clapper discs), to the left and right of the diaphragm assemblies are the 15 hex head cap screws that join the head/bell assemblies together and the 5 allen head cap screws that install in the heads and tighten to prevent movement of the back caps. Above the diaphragm assemblies is the base or manifold, to the left of the manifold are the 5 diaphragm seats or nozzles and the "o" rings for them, to the right of the manifold are the baffle discs or diffusers, and lastly at top the bells.

It could have gone further: each diaphragm assembly will break down into 6-8 individual pieces, depending on which one.
