Merideth,
What a curve ball! Was Mr. Allen transferred to the Pacific after the war ended in Europe? That might explain the photograph.
Anyhoo, I found out the folowing about Mr. Allen.
He is mentioned a few times in Merle Olmstead's book
"The 357th Over Europe" - The 357th FG in WWII.
He is, indeed, listed as a member of the 364th FS, codes would be C5-"x". The squadron color was yellow and the rudders of each aircraft, if painted, would have been this color. As to the exact code and serial# of an aircraft, I've found nothing with his name on it.
He is listed as having participated in the downing of three aircraft:
_Date___________Rank_______________Claim_________
20th June 1944 -- 2nd Lt. Merle F. Allen Jr. ------- .5 (Shared kill)
29th June 1944 -- 2nd Lt. Merle F. Allen Jr. ------- .5 (Shared kill)
13th Sept 1944 -- 1st Lt. Merle F. Allen Jr. ------- 1
No aircraft types were listed for the downed aircraft, but the 20th June victim was an Fi 156 Storch.
The encounter report that you found on your search was taken verbatim from this book, and there is another describing Mr. Allen's participation in the destruction of this Storch.
June 20: The apprehension of the crew of an unarmed Luftwaffe Fieseler Storch in a sky full of Mustangs can well be imagined, and on this date, the worst fears of one such crew were realized. Nick Frederick in his encounter report:
"I was flying GREENHOUSE Red Three and after I had destroyed an Me.109, I saw several P-51s chasing a Fieseler Storch on the deck. I got behind Lt. Merle Allen and saw him fire, observing strikes on the fuselage. The Storch kept flying and since my guns were jammed, I forced the Storch into the ground by flying several feet over him. The propwash evidently spun him in. The plane broke into many pieces." (Merle Allen then strafed the wreck and the two shared the claim.)
I think someone gave one of these links before but here's a couple for some good sites on the Yoxford Boys.

http://www.cebudanderson.com/ Bud Anderson's (Old Crow) site. This one has a link to a 357th site where there is an ongoing and HUGE modeling project. Perhaps you can find some info there. I haven't looked at this site lately, but I'll see what's there.
I'll keep looking for more info!
