There's not much in Hendersonia about his two sides on Edison. Just this:
"It has been erroneously assumed that Edison's recording studios were in Orange, N.J. Although his factory and pressing facilities were in Orange, his studios were in New York City at that time. These records are a quarter-inch thick, are vertically cut, and can be played only on an Edison diamond disc reproducer. Those who have such a machine, however, will be rewarded by the finest fidelity of the acoustical era, and by playing times of over four minutes per side."
Walter Allen provides additional information on the two sides, including identification of soloists.
There's another Henderson book, pictured below, but it has no information about Henderson's recordings on Edison.
