When, on 1 January 1933, the newly-established
aviation department of the Linkoping-based railway
wagon and carriage manufacturer, the AB Svenska
Jarnvagsverkstaderna (ASJA) acquired the assets of
Svenska Aero AB of Lidingo, it took over the continued
development of the latter company's S.A. 14 Jaktfalk
(Gerfalcon) single-seat fighter. An improved version of
the J 6A was evolved by ASJA as the J 6B Jaktfalk II,
this being offered with Armstrong Siddeley Jaguar or
Panther engines, or the Bristol Jupiter. The Jaktfalk II
retained the revised wing structure and lengthened
fuselage of the J 6A, to which were added redesigned
horizontal tail surfaces from which the bracing struts
were eliminated. Seven were ordered by Flygvapnet
with the supercharged nine-cylinder Bristol Jupiter
VIIF radial rated at 520hp at 3050m, armament
comprising the standard paired 8mm synchronised
machine guns. The contract was placed with ASJA on 1 May 1933, and the seven aircraft were delivered
during the following October-November, serving,
like the Svenska Aero-built J 6s and J 6As, with
Flygflottiljl at Vasteras. Two of the J 6B Jaktfalkar (together
with a single Svenska Aero-built J6A) were
donated to Finland in December 1939, subsequently
serving in the fighter training role.

Seems like the picture is in fact of the specimin on trial for the Norwegian Amry Airforce, in that case the engine is an Armstrong-Siddley Panther XI. However, in trials it produced too much vibrations and could not be used as a float plane and was not adapted.
