Provenance This loupe was owned by entomologist B.R. Coad, possibly for examining insects and insect damage while in the field. Dr. Coad was based at the USDA's Delta Lab in Tallulah, Louisiana, in the 1920s. He headed Delta's crop-dusting operations, based in Monroe, Louisiana, from 1930 until his death in 1966.

John L. Ritter acquired the loupe after he went to Monroe in 1966, to audit the books of the Delta Agricultural Division (formerly the Delta Dusting Division) in preparation for Delta ending crop-dusting operations. Esther Tarver, Coad's long-time assistant sent Ritter the magnifying lense in Summer 1967.
