Bleeds for Secondary Valves
By John Grant

[ Ref. 130612 MMDigest, Aeolian Primary Valves Have No Bleeds --

Typically, the secondary pouch has no bleed because it is exhausted
back through the channel to the primary valve.  Are the (secondary)
bleeds drilled in the typical Aeolian light green celluloid discs?
What are the diameters of both pouches and the primary bleed?
