I realize that I did not post the base that I refinished for the Singer 99 that was resurrected from the scraps that were delivered due to poor packaging (once was a whole machine) and the Spartan that I turned into a handcrank. I have another Spartan in its original green case, but this one came in a broken bakelite shell. I bought the case bottom from Cindy Peters, email@example.com who is a wonderful seller of parts for antique and classic sewing machines. It came unfinished and I used Minwax antique oil finish, at least 4 coats, and it is just terrific. It is cherry wood. I am going to buy another, but here are the 99 and the Spartan in the same base. Converting to the handcrank was easy. I bought a vintage spoked handwheel, unscrewed the old handwheel, put the vintage one on, bought a reproduction handcrank, unscrewed the bolt for the motor, removed it, and that was it. The machine itself was extremely dirty and gunky, but now it is just terrific.
