I am now completing the final steps for the shaft axial retainers and radial bearing. I greased the bearings and tightened the bearing caps. During cleaning of the grease cup I noticed that it holds a 1893 patent mark. This would indicate the possible age of the machine. The machine also has two other patent marks. One on the bed stone that reads 1870 and one on the grease cap that reads 1889. My guess is that the machine was built after 1893.
