Hey, new guy here. Found Grandpa's Baker 1897, thought we'd lost it long ago. Hoping for help with two questions. (1) I want to get the rust off (plenty good advice on that around here, thanks!), but I don't know how the furniture comes off. (2) The screws that hold the hammers on are missing. They're 6-40, should probably be 1/4" - 3/8" long, with round, slotted heads. Checked Numrich, Midway, and a few others w/o success. Any help appreciated.
