I found some information about the two-seat Hurricane from the web site

The first of the two two-seat Hurricane Mark IIC trainers for Iran, mentioned above, performed its first flight on 27 September 1946. The trainer originally had tandem open cockpits, but the turbulence around the forward cockpit made the rear cockpit extremely drafty, and so a bubble canopy was fitted over the rear cockpit. The trainer originally retained the four Hispano cannon, but they were later deleted. The Soviets also field-converted some of their Hurricanes to tandem-seat trainers, with open cockpits, but few details are available about these conversions.
