GAL.26

Type: light twin-engine 4/5-seat transport aircraft
Powerplants: two 90 hp Cirrus Minor I engines
Date: 1936

The GAL.26 was a one-off aircraft, an ST.25 with different engines and trousered main undercarriage. It is said that it was converted from an ST.25 but what airframe was used for the modifications is not known.
NOTE: this was the first aircraft to carry the "GAL" prefix instead of "ST" as founder H. J. Steiger had just left the company.

According to member Ursrius:
Quote
Ah, that old red herring!
I have only seen two photographs that purport to be it, one in Aeroplane Spotter for June 26, 1948 and the other in Air Enthusiast May/June 2001.
However, comparison with photos in Aeroplane for 2-Jan-1935 show that the Aeroplane Spotter photo was most certainly that of the prototype ST-12. The Air Enthusiast photo (the one you show) would also appear to be from the same time and the hanger behind seems almost certainly to be GAL's at Croydon, the GAL.26 being built at Hanworth.
The GAL.26 was the ST-25 Jubilee G-ADWI modified with Cirrus Minor engines in 1936. The only photograph I have seen that I believe to be the GAL.26 was in a Cirrus Aero Engines advert in Flight, November 19.
