I am looking for the bandspread flywheel for an SX-28. It is cast iron, 2-3/8" dia, 5/8" thick, 1/4" hole. Does anyone have one that you would be willing to sell, or know of a commercial source. I think they are cast iron, not lead. If there is a commercial source that might be useful for other rigs as well. Thanks 73 Bob Krassa KC0TDS
