Narrative:

While acting as sic on a part 135 charter flight, I arrived approximately 1 hour prior to scheduled departure, greeted the captain who at that time was reviewing the flight manifest and completing the weight and balance for the flight. I proceeded to obtain destination WX, preflight checks of the plane, ensured that the fuel load was correct and restocked the aircraft with supplies. Upon arrival in the flight office, I took the flight can and captain's headset and placed it in the aircraft. The flight originated on time and was uneventful during both legs. Upon return to our base, the flight department charter manager questioned us as to the whereabouts of the MEL form 105 and indicated that it was not in the flight can for this flight. Both the captain and I examined the can and found the form in question to be missing. The deferred item was for the oxygen bottle that had been placarded as removed for service. Both the captain and I noted this during our cockpit inspection and assumed that the required paperwork was on board.
