We have 2 Metal / plastic Pullies Vintage items. The large one measures about 3 7/8" in H x about 2 5/8" in w at it's widest point x about 1/2" in d on the pulley. This one is completely plastic. The smaller one has a plastic pulley wheel and a metal frame holding the wheel. This one measures about 2 3/4" in h x about 1 3/8" across the wheel with the wheel dept being about 3/8" across. I believe the frame is galvanized metal. There is a touch of rust/tarnish on the top.
