The "Anastigmat" label predated the "Ektar" name, and dates back as far as when Kodak first started making their own high-quality lenses around 1930. They were often identified by a number, e.g. "Kodak Anastigmat #33, 150mm".
The Ektars were introduced around 1940, the first large-format ones were labeled "Eastman Ektar" and were uncoated. By 1945 they were coated and the f/6.3 series was called the "Kodak Commercial Ektar"; the f/4.5 versions were just "Ektars". Now to my point- some uncoated Ektar lenses were sold as "Anastigmats" at the same time, which I imagine is what your lens is. It should be a fine performer on 8x10, just a bit lower in contrast than a coated lens. To ramble further, you can tell the age of the lens by the two-letter CAMEROSITY (1-9+0) code in the serial number.
