Unfortunately, my French references are very thin. Farman would be my first guess.

Dang, didn't think it would be <i>that</i> easy.
Yup, Lefty, you've got it. The SV-10 was built by my local aircraft factory, the Stampe-Vertongen works at Antwerpen-Deurne airport (now even more local - I'm moving to a house a ten-minute walk away from the airport!). It was built to a 1934 specification for a multi-purpose bomber/reconnaissance/heavy fighter aircraft by the Belgian Military Aviation, which also resulted in the rival LACAB GR.8 bid.
Designed by Georges Ivanow - the designer of the Stampe SV-4 - the aircraft was a sesquiplane powered by two Rhone-Gnome engines, capable of 360 km/h at 15000 ft. It had a crew of five, two flying crew and three gunners. Its armament were a front and upper turret with twin Browning mounting, and a retractable belly turret with single Browning mounting. The front turret could be equipped with a 20-mm gun, and the plane could also carry 600kg of armament.
The prototype did its first flight on October 4th 1935, with the constructor's son Leon Stampe at the helm, and designer Iwanov as a passenger/engineer. This flight was a success, and the next day, the prototype made a second flight with the same crew. However, at an altitude of 800m (2600ft), the aircraft went into a spin, crashing not far from the airport. Both crew were killed, and the project did not survive the demise of its designer. Stampe returned to producing light biplanes, selling SV-4s and SV-5s to both military and civilian users.
As a footnote, both the SV-10 and LACAB GR.8 proved to be outdated designs even during their design phase, especially when compared to what the UK and Germany were designing and building at the time. Both programmes were effectively still-born, with the sole LACAB GR.8 being grounded after a landing accident in 1938, and eventually being destroyed during the German invasion of May '40. Even the design the Belgian Military Aviation eventually purchased, the Fairey Battle, was far from ideal... but that's another story.
Your turn, Lefty!
