Just picked up another restoration project, as if I did not have enough with the 4 I already have waiting. This one needs to be saved as if I am not mistaken, it is one of the original 250 shipped out October 15, 1947 to Montgomery Ward stores on the West Coast. It does answer some questions about the original 10E and the pre-production one shown in the original manual sent out with them. It has the first 10E headstock not the one shown that Everett has named the Model 10. The base, arm, headrest, carriage, tie bar, etc. are the same ones common to the 10E. Of note is the 8" Lathe Tool Rest. It is the one shown in that original manual with it's post to mount it in the arm a screw in part. It did not have an arbor with it so I am unable to answer the question about an earlier arbor like the one shown in the original manual. I will add that it is in very good shape for a 70 year old machine and has very little rust. More in the PDF below.
