Narrative:
I received a call from my chief pilot concerning the aircraft I ferried the previous night. The originating crew following our ferry flight reported that the crew oxygen system was turned off. I am well versed and knowledgeable with the B737 and all our operating procedures; including the crew oxygen system preflight. I thought I had completed all the required checks. However; in light of the other crew's report; it may be possible that we missed completing the preflight of the oxygen system; and also may be possible that we missed the crosscheck during the before start checklist. The ferry flight in question was the second aircraft and flight within 30 minutes. It is possible that I was distracted during my preflight duties due to factors such as: unfamiliar uncontrolled airport; late at night; aircraft was a 'thru-flight' powered up upon our arrival; extra paperwork/calls to dispatch; and the captain's offer to complete the walkaround. Although I did not feel pressured or distracted at the time of the preflight/checklist; the operation was far from a 'normal' sequence of events typically found during revenue operations.
