re: Col Kavoada etc.
1. The MaHari Vayl ruled that we pasken that that Col Kavoda Bas Melech Pinima is not the din. He has an offenna gemora in Gitten. The Ramoh paskened like the MaHari Vayl.
2. The mesorah of B’Nei Ashkenaz is like the MaRi Vayl, witness all the doros where the women ran stores and businesses to support their husbands (incl. many gedolim) learning.
