In replies #31 and #34 of this thread, I asked:
1. In the photo that Richie Conroy attached to Reply #29, what is the equipment item mounted above the starboard 118-gallon tank?
2. What did the enclosure for the Bendix loop antenna coupler look like?
Since posting the questions I’ve found a photo that suggests that the item mounted above the tank is the Bendix loop coupler.
See the attachment, which combines a crop from the Reply #29 photo with a crop from a photo showing Cyril Remmlein holding a Bendix loop coupler, the latter photo from the book by the Long’s. In the two crops, note the crinkle finish, the mounting plate at top of enclosure, and the cable connector at top right of front panel.
If the loop coupler supposition is correct, the photo dates to 6 March 1937, or after, and begs two more questions:
3. What are the front panel details for the coupler (labels, purpose of switches, other controls and connectors)?
4. What is it that is partially revealed at bottom-right in the Reply #29 photo?
