G.I Prototype – powered by two Hispano-Suiza 14AB-02/03 engines; one built, c/n 5419.

B 26 – Swedish dive bomber variant of the G.1 Mercury. Originally designated B 7, 18 were ordered with 77 (later 83–95) more planned.
Due to the cancellation of the 12 Swedish S 10’s (Breguet Bre 694) by the French government due to the German invasion of France it was decided to let the first batch of 12 aircraft become reconnaissance planes called S 13.
The B 26 was unique compared to the Dutch variant.
Its armament would consist of four 13,2 mm akan m/39 auto cannons in the nose and an 8 mm ksp m/22-37R machine gun for the gunner.
It would be equipped with a bomb bay that could hold 8 x 50 kg bombs or a single 250 kg bomb with a bomb fork along with hard points under the wings for 4 more 50 kg bombs (2 under each wing).
The B 26 could not be delivered to Sweden due to the invasion of the Netherlands.
A mock up was apparently built by Fokker.
S 13 – Swedish reconnaissance variant of the G.1 Mercury. 12 of the original 18 B 26’s where re designated S 13 and where reordered with glass domes called “bath tubs” where a third crew member would sit and scout.
Armament would be similar to the B 26 but 2 of the 13,2 mm akan m/39 guns where replaced with 8 mm ksp m/22 ones.
The glass domes could also be removed and replaced with a bomb bay.
Just like the B 26 none was delivered due to the invasion of the Netherlands.
