EROS Crew Oxygen Masks
 

Can anyone help with a source for buying reconditioned EROS masks and stowage boxes.. .. .I've already contacted the manufacturers, who currently have a lead time of 36 weeks for new gear!!!. .. .I am specifically looking for 2 x MF10-02-11 masks and 2 x MXP410-1 stowage boxes. They are needed for a new B737-700 simulator, and need to be operational, but not to the same spec' as on the real A/C.. .. .All replies gratefully received!!
