The Model T is the only one I see. If I was going to replace the gear I would use ether laminated or metal. The macerated gear is chopped up short fibers/binder compressed to make the gear. (If you understand how paper is made, same thing) The laminated is layers of woven fabric/binder compressed. The laminated are more $'s but you are buying a better product. How to tell the difference; the laminated you can see the weave from the fabric the macerated is smooth a bit like paisley print gone wild.
