It was a Cable Nelson and the serial number suggests it was from the late 1930s. I failed to take before photos only in progress photos, but they are available on the internet. It had seen better days so I had few reservations about converting it.
Even after I dismantled it and removed the large metal harp I was amazed at how heavy it was. YouTube has multiple videos about dismantling pianos, but one should pay special attention to the safety precautions because the strings are under extreme tension.
