The US Navy acquired five COA-1 amphibians from the US Army. Receiving the OL-2 designation, they were intended for the 1925 MacMillan Arctic Expedition, with Richard Byrd leading an aviation element of three Loenings: NA-1, NA-2 and NA-3. NA-3 arrived at Squantum on 11 June 1925 and the photo is assumed taken that day. The pilot was Floyd Bennett. Byrd liked Bennett and put him in NA-1. The following year they headed for the North Pole together in a civilian Fokker F.VIIa-3m, Josephine Ford, which Byrd had coded BA-1. Photo by: Leslie Jones / Boston Public Library

The TG is described as a gunnery trainer. Five different prototypes, designated TG-1 through TG-5, were built. In the TG-5 the fuel tanks were moved to the central float. The uncropped photo shows the plane with a Loening OL-2 of the 1925 MacMillan Arctic Expedition, A6982 / NA-3. The date is not certain, but Boston Herald photographer Leslie Jones presumably came to photograph the arrival of NA-3 at NAS Squantum on 11 June 1925. Photo by: Leslie Jones / Boston Public Library
