Graflex Optar Large Format Lenses

Folmer Graflex filed for a trademark on Monday June 22nd, 1942 for the name "Optar".  In their filing they stated that the name "Optar" was first used on May 8th, 1942. They were awarded the trademark for "Optar" on October 27th, 1942.  So the oldest Optar lenses date to 1942. 

Serial numbers range from at least 289,xxx to 929,xxx.  I have not been able to find any source that can date Optar lenses based on the lens serial numbers.  If you have an Optar lens that the serial number is outside this range please let me know.

Here's a chart of Graflex Optar large format lenses.  As you can see it is missing a lot of information.  If you have any information on the Optars please send it to me so that I can update my chart.  Thanks!
