A320 flight crew is informed after the fact; that they may have flown an aircraft on a part 91 ferry...

Narrative:

We were tasked with a part 91 reposition flight and the flight was routine. After a second reposition flight on a different aircraft and while in a taxi to our overnight hotel we received a call from the crew taking the original reposition aircraft. They asked us if we had noticed any discrepancy with the overwing emergency exit door 'slide armed' indication. I advised them that I did not recall any malfunction and the slides themselves do not generate malfunctions to the fwc unless a cover is removed from the overwing exits. As we were a reposition flight only we did not arm the slides due to concern over inadvertent opening of an armed door during a non-normal operation. If the overwing slides were not armed it escaped our notice during the flight. We were only advised of a possible situation by the crew subsequently flying the aircraft we had repositioned. Failure of the maintenance facility to rearm the overwing emergency exit slides may have been a factor; however as I did not notice any slide malfunctions and we did not arm the slides prior to departure I cannot say that this may be the case. It may be helpful to add the overwing slides to the post maintenance inspection procedures and possibly add a slides armed item to the before start or after start checklist.
