ok fur cloaks you can get panther and wolf ones from empire knightly order. Tassests unfortunatly you can't buy (in my extent) becuase hey come built in on models (mainly empire) shields you can gets from GW on most sets and some as bits. the Aguer and Matriach you can get from GW here are the links for:Fur
Cloaks or Here
(at the bottom)
Sheilds are Here
or in any regiment that canhave sheilds.
Ok if you are Desprate (i mean really Desprate) you can salvage them off of empire greatswords/state troops or make them out of greenstuff.
And finally your Matriach (use the SUpior for an Aguer) here
