Hydroland tank / Ocean tank

I came across these photos of an American "hydroland tank/ ocean tank" carried aboard USS Wyoming no later than February 1924, as part of "the greatest peacetime maneuvers ever held by the land, sea and air forces of the United States," or so some papers claimed.

Besides the armament (75 mm Gun M1897) and speed (14 knots) of that tracked vehicle, I have found nothing about it, which probably means I am not looking in the right place.

It was then hoisted aboard a waiting submarine prior to its launch toward the shore, then "As the "mother ship" submerged, the Christie tank proceeded to shore. Unable to maneuver through the heavy surf, the vehicle returned to the Wyoming without landing. The next day, when the surf had subsided, the Christie amphibian once again left its mooring aboard the submarine and made a perfect landing. Despite the fact that the vehicle came ashore after the exercise had been declared officially finished, Cole stated that the tank possessed the capability of being developed into an extremely valuable weapon, especially in association with landing operations."

I've attached a picture from the Getty website.
