Pilot R L Hess , B-17 " DOTTY " 379th Research help needed

The list of aircraft names in the 379th BG Anthology does not include a 'Dottie".  Wallace Forman's B-17 Nose art Directory lists something like 24 different B-17s named 'Dottie" or some variation of Dottie, but none with the 379th.
 
Follow this link and scroll down to the bottom of the page, "search #1231", and you will see Roland L. Hess listed as a Pilot with the 379th.  This may or may not be your man.  Does your jacket show a serial number anywhere, or just the name?

Boy, I have to say after looking at the missions shown on the jacket and the missions shown on the 8thairforce.com site for Roland L Hess that it would appear to be a "close" match but maybe no cigar.

While the jacket blurb mentions 29 missons, there are actually 35 shown on the jacket as repeated missions to the same location are shown as multiple "bomb bursts" with the same target name.  The ones that don't seem to match that I can see  appear to be "Paris" , "St Lo".  There are probably others I can't read.   I wonder if I am misreading the jacket names, or they were an alternate target bombed by part of the group and did not appear on the main mission list.   If this is the wrong guy, then I think we are looking for someone who flew  at about the same time.  I found St Lo  was bombed on successive days, (July 24 and 25) at the start of operation Cobra.  Also there are two missions shown on the jacket to Munich, while the mission list has only one.  
 
There is an odd thing regarding the target,  Houdan which is shown on the jacket.  According to the Air Force Chronology, Houdan (Houden) was bombed only once, on 7 August 44  by 14 planes.   Houdan appears on the mission list for R L Hess from the 379th on 7 August 44.   If only 14 planes bombed the target, and one of the planes was from the 379th, what group(s) were the other 13 planes from?  How likely is it that those 13 planes came from some other groups?  
 
What do you think?

Here is the what is recorded on the mission narrative:
 
On 07 August we were scheduled to bomb Gennevilliers, France, furnishing three groups as the 41st "B" wing. As the primary was covered by clouds, the lead and high groups hit Maintenon with fair to good results. The low group was unable to pick up the secondary objective in time, so they bombed Houdan. Flak was very heavy and accurate over the primary target, resulting in considerable damage to our aircraft.
Where is the photo of the jacket?

I too count 35 missions on the jacket. However if my earlier post cleared up the Houdan question. Is the Paris mission the only question that remains to ascertain the validity of this being R.L.Hess' jacket? 

There is/are  the St Lo mission(s).  

This poses a question about spares. I have noticed in the mission narratives the mention of  (X) number of our aircraft where used as spares. I  guess to fill in and supply the appropriate amount ships & explosives needed for that target.  At times they mention which group & the assigned target for that group also sometimes it just says used as spares. The fact that they were from the 379th but bombed another target/city with another group is not listed on the Missions list for the 379th . I guess this may be because the main groups of the 379th bombed their primary and or secondary targets/cities that day but the aircraft used as spares in the other group(s) I'm guessing but this spare designation does not qualify it as an assigned mission for the 379th???? Could this be the reason for the jacket having different cities/missions than cited on the 379th missions list????
