The Ripon-Bloch RB-131.2 is designed to the Ministry of Aircraft design specification BH.0/33, subsequently to become the BH.4/33. Six other designs were presented from the Accrisius, Spartan and Roth firms along with 2 additional designs from Ripon-Bloch, essentially earlier RB-131 derivatives.
Here is the Ripon Bloch RB-134.2 in all her glory. A mix of the streamline, the sublime and historical French uglyness (sorry Stuart!). James based her on an Avro Shackelton mixed with a hint of Piaggio P.108. Peck away
