She was built as KARAMANA for F.B. Cadman in 1923 by Bailey & Lowe to a design by Hacker. KARAMANA = CADMAN in pig maori.
She was later bought by Auckland Grammar School teacher P A S Stein and rebuilt as per the pic below. She was fitted with a war surplus 6 cyl Green sohc aero engine producing 120-140bhp, bore 5.5 ins, stroke 6 ins (you work out the capacity). She was pretty radical, a far cry from her current. configuration.
