You are bidding on a new old stock vintage RCA type 6E5 radio green eye indicator tube, branded Packard Bell.  It is nice bright new tube which bears the RCA 274 manufacturer code.  The box and base are labelled Packard Bell.  I took photos of the brightness while testing in my TV-7 tester.  A new tube tube brightens up any set.  Shipping weight is 8 ounces.   Please see my other auctions for more interesting radio and audio items, and tubes.
