[NW Mailing List]

 Going from memory here (a very dangerous enterprise), I seem to recall that this addition was some sort of counterweight.  Anyone else ever heard/read this??

Does anyone know the purpose of this piece? I have found an image of a J in '57 with this still there, so it seems to have likely lasted until the end of the 600-604's.
