Stanley Sweetheart No. 2 Miter box with Sharpened Saw

Stanley Sweetheart No. 2 Miter box with a freshly sharpened saw. The patent date is 1-3-12. The saw is 24" with a depth of cut of just about 4". All the parts for the miter box seem to be there except for one screw on the top of the front post (see picture). I did a couple of test cuts and it works great. The saw is clean and ready to go. The miter box is fine but could use a little more cleaning and lubrication.
