SAm2- The question in 96 is indeed a strange qustion. But which mefurash gemara are you talking about.
Either way I found a Reb Moshe on this see http://hebrewbooks.org/pdfpager.aspx?req=919&st=&pgnum=139
see also: http://hebrewbooks.org/pdfpager.aspx?req=46217&st=&pgnum=232&hilite=
(but I don’t like when seforim say things as a davar pashut with no mekor)
And is anybody else annoyed that from the many wonderful seforim hebrewbooks has they are missing most of the chalokim of the normal printing of shulchan aruch with nosei keilim.
