Red Baron Kill

My grandfather, Harold Saville, RAF squandron 1, was shot by the Red Baron over Germany and escorted to the French border where he crashed. I do not have a date or location. Harold awoke several days later in a hospital in England, survived the war and lived until 1950. I would like to know if the incident was documented and if included in the Red Baron's kills, what number kill.

* Sorry, Prop, but I checked 3.5 sources and came up with nothing (the '.5' is when I checked the score of the Baron's brother, Lothar). There is no Saville among them; there is an SE5a from #1 Squadron RAF, victory #77, but even this particular victory is in dispute (and the Baron, for whatever reason, enclosed the aircraft type in quotation marks in his report; it's been suggested that even he wasn't sure as to the type). This is not to say that no aircraft from #1 ever fell to the Baron...
* What makes identification so difficult in this case is that we don't know "where or when"... is it possible that you could give us more details: what aeroplane did Gramps fly? Where was he stationed? Was he a pilot or an observer? How did he know that it was the Baron?
* Of course, the intrigueing possibility exists, as it always has, that this was one victory that the victor wasn't aware of; this would not be the first time that that happened...

Thanks so much for your reply. Apparantly he did not speak much of the war to my mother other than the occasional comment like ' Billy Bishop is a fraud'. As such I don't have any real details of the incident. I do know he often flew two seaters and dropped and recovered 'spys' behind German lines. I believe he did most of this flying early in the war, including many flights before aircraft were fitted with a gun. I do have his ground school notes which are facinating, but unfortunately no journal. Thanks agian.
