We have a Metal and wood crumb set in the original package from the 1970's or so.  The pan and brush handle are made of wood stained very dark with the bristles being nylon? and the pan being stainless steel.  The pan measures about 5 3/4" in L x about 4 3/8" across the widest portion with the brush measuring about 2 1/8" in L x about 3 3/8" across the widest point above the bristles.
