This is a new NOS FX-4 Flash Tube by E.G.&G.  All leads and items is new NOS condition.

Please note:  Not all printing may be perfect.  These tubes are all NOS and original from the factory, however, do not expect them all to have perfect print due to the age of these tubes.  This is an inherent trait of most tubes this old.  These are more than likely the finest preserved of this type available anywhere.
