H. H. "Steam" Stewart knew about Abner Doble as early as February 4, 1926 when he started collecting newspaper articles on Doble's stock swindle trial. Stewart almost certainly heard of Doble when he spent three months in Newton, MA in 1924.

Stewart and his family socialized with Abner Doble on his trips to New Zealand during Doble's steam bus effort. He was particularly interested in steam busses and followed the progress of other efforts.

This information is loosely organized by the various Doble vehicles identification numbers.

Stewart Family & Doble's Mistress Stewart Family & Doble's Mistress

H. H. Stewart and family, January 26, 1932. From left to right, Abner Doble's wife, Evelyn Stewart, H. H. Stewart, Keith Stewart, Colin Stewart, Hugh Stewart. Photo taken on the front lawn of the Matai Road , Greenlane, Auckland home of the Stewarts. Given Abner Doble's absence from the photograph and his wife's inclusion in the photo, it is quite likely that Abner Doble took this photograph with Stewart's Camera. Source: Stewart Archive.

Dobles in Front of H. H. Stewart's Home

This series of snapshots shows the two Doble vehicles that Abner Doble brought to New Zealand, E-13 and E-24. Doble E13 came to New Zealand some years before Abner Doble's visit in the early 1930s.

H. H. Stewart poses with Doble E-13 outside his family's home at 24 Matai Road, Greenlane, Auckland, New Zealand. Doble E-13 came to New Zealandsome years before Abner Doble's first visit. Abner Doble very likely took this photo with Stewart's camera. Source: Stewart Archive.

Testing the Model F Doble Engine

These six images appear to date from early April 1931, as two are date stamped April 16, 1931. Happily, they are identified on the reverse as engine tests for the Doble F series engine. The writing appears to be that of Warren Doble who likely took the photos and gave them to H. H. Stewart.

These photos and other published information make it clear that Warren Doble was in charge of the factory testing of Doble systems.

Unhappily, one image is numbered 22 and one is numbered 57, suggesting that Warren Doble took a great deal more photos that have not survived.
