Let me also add that when the closing of approximately 50 companies and the lay off of some 300 FDNY Firefighters came about due to a budget crisis during the height of the FDNY War Years, that is when the FDNY requested those members no longer take part in such a system.
A friend of mine back then was an Auxiliary Firefighter in Engine 60/Ladder 29 and he had told me about that at that time. That friend is now living in Virginia and on this site his user name is "BFD151". Now a retired Bridgeport, Ct Firefighter.
We have a few members on this site who were Auxiliary Firefighters, including "Johnd248". Also I know that "AuxWarYearsCapt", Doug M., was a member in a Queens company.
