Thanks.? Based on an assumption of constant production, it would have been made in late 1968.? However, if they were still selling as many in the 1960¡¯s as they had in the 1940¡¯s, they wouldn¡¯t have stopped making them.? So it was made earlier, maybe in the early 1960¡¯s.
Here are a couple photos of their current condition. The Atlas is complete and well oiled. The Sears is covered in saw dust as it had been sitting in a wood shop for years. There is no id plate, neither on the end nor the back. It is complete except for a motor. Both are sitting covered as I try to convert a 50x6 room along the front of my house from a greenhouse to shop space.
