If you are looking for bulk metal wheels I know Intermountain has 33" an 36" in a silver plated style. LBF also has bulk wheels in 33" and 36" sizes but theirs are a brown color, a littel more realistic and only about $50 dolalrs for 100 compared to $75 dolars with intermountain for the same amount. Also branchline just realeased some packs of 33" and 36" wheels I think enough to do 3 cars for $10
