Type Description
- Type 626
- Two seat, multi-purpose development of the later model Type 621, offered with conversion kits to make it suitable for initial flying training, or bombing, photographic, gunnery, wireless, night flying, navigation, blind flying and seaplane instruction. Basically identical to a late model Type 621, it featured a third cockpit behind the rear seat of the 621 and accessible from it, though the aircraft was only be flown with two occupants. This additional cockpit was fitted with a Scarff ring for a machine gun. A fixed, forward firing Vickers machine gun could be fitted on the port side of the forward fuselage. The removable side panels on the fuselage were more extensive than on the Type 621, extending from the engine bulkhead to the gunners position, and the forward fuselage metal skinning extended aft past the front cockpit. Some aircraft featured an additional fuel tank above the wing centre section. One 215 h.p. Armstrong Siddeley Lynx IVC or 270 h.p. Armstrong Siddeley Cheetah V powerplants.
- Type 626 Prefect
- 2 seat navigation trainer variant of Type 626 to meet Specification 32/34. This was basically the Type 621 brought up to Type 626 condition, but without the third cockpit, and equipped with a tail wheel and modified aileron circuits. One 215 h.p. Armstrong Siddeley Lynx IVC powerplant.
- Type 637
- Lightly armed frontier patrol variant of the Type 626, with rounded wingtips, giving 4 ft greater wingspan. The front cockpit was eliminated and replaced by a long, tunnel-like windscreen incorporating the telescoping gun sight. A Vickers machine gun was located in the upper coaming forward of the pilot, and a large reserve fuel tank replaced the lower part of the forward cockpit. One 270 h.p. Armstrong Siddeley Cheetah V powerplant.

Notes
- Three Ex Austrian Type 626 appeared on the German civil register as D-IPMC, D-IHVD (C/n 983) and D-ISCX.
- Jackson [1] gives c/n 797 as a Type 626 to Lithuania, but this c/n belongs to a Type 638 Club Cadet. This author believes the correct c/n here should be 979.
- Rivas [9] gives 30 serials for aircraft used by the Chilean Army, though from Jackson [1], only 20 c/ns have be identified, with serial 1 to 20. Certainly serials greater than 20 have been identified photographically. From Dan Hagedorn [10]: "While the Chilean Army routinely issued serial codes in strict numeric order to newly acquired aircraft in the late 1930s prior to adopting the familiar four-digit system, it is clear from existing records that they apparently assigned NEW numbers to rebuilt (composite?) aircraft and I strongly suspect these to be the sources for the numbers known above 20."
- In January 1942, three aircraft, Π4 (c/n 933), Π6 (c/n 935) and Π16 (c/n 1105) of the former RHAF managed to escape to Egypt and were impressed as HK833 - HK835, but serial tie-up is unknown.
