Photo assumed taken at the Bell factory, then still in upstate New York. Ordered as an XR-13 but delivered as a YR-13 in 1947 and redesignated as a YH-13 in 1948. Later N4017A, CF-NNA and N9066J - it was modernised several times and ended as a Bell 47G-2.

'Bell - The Modern Magic Carpet. Designers and Builders of Helicopters for the United States Army Air Forces, Army Ground Forces and Navy. Utility Unlimited - The Bell Helicopter.' An early military R-13, a Bell 47B prototype and a Model 42 on display in the Bomber Plant at CLE, the future International Exposition Center. Bell had high hopes for the Model 42 five-seater but the 47 generated far more interest. Three other 47s were flying outside. Photo from: Bell Aircraft Museum
