30-40 passengers is a LARGE airliner for the 1930s, given that the DC-3 only carried at most 32 passengers. The DC-4 carried 52, but was uneconomical in service.

Does Siam actually have enough air traffic to merit anything larger than a DH Dragon Rapide could provide?

I have an airliner in mind.

Ju-90.

I doubt the Ju-90 was that much more efficient as an airliner than the DC-4 was (though the BMW-132 would be cheaper to run than the P&W R-2000, just because it's a smaller engine) , but Junkers has built the Ju-90 in very small numbers, and if Siam wants some all they need do is contact Junkers.

Currently, Junkers is building a variant of the Ju-90, the Ju-90S, for demonstration to the Luftwaffe as a possible heavy bomber. This plane, after being shown at the Hendon Review, is awaiting re-engining with BMW-801s replacing it's BMW-139s.

As far as the request for a smaller aircraft goes, Junkers can offer the Ju-52 (rugged, absolutely reliable, and cheap).

De Haviland can offer through DH Siam;

De Havilland D.H.91 Albatross; designed as a transatlantic mailplane to Specification 36/33 the first prototype of this sleek monocoque wooden aircraft first flew on 20 May 1935. Fourteen are on order for Imperial Airways, six as D.H.91 mailplanes and the remaining eight as 22 passenger airliners for European routes. QUANTAS brought two and Persia received eight in 1936. Dimensions; 105/ 71.6/ 22.3/ 1,078 sq ft; 4x 525hp de Havilland Gipsy Twelve; max speed 225mph; range 1,040 miles and service ceiling 17,900ft.

On the drawing boards at Hatfield is the De Havilland D.H.95 Flamingo; this private venture design that will fly in December 1937. This all-metal high-wing airliner will carry 17 passengers and a crew of three/ four. Designed for economical operation it is capable of operation from rough strips with limited facilities. Dimensions; 70/ 51.7/ 15.3/ 651 sq ft; 2x 930hp Bristol Perseus XVI; max speed 243mph; range 1,345 miles and service ceiling 20,900ft.

China offers for the Shennong Dragonfly for the small airliner request.

The Savoia-Marchetti SM.75 nicely meets the spec as is readily available at the current time. The picture above shows one of the aircraft in service with Ala Littoria. Last year one of these aircraft took part in a famous Atlantic crossing flown by Italo Balbo. A very reliable machine with good handling characteristics and a short take off. A larger version with increased passenger carriage is currently under design to be powered by Alfa-Romeo 135 engines.
