Looking for portraits - 78th FG 1943

I'm looking or copis of portraits of some key menbers of the 78th FG in late
'42 and '43. The photos were lent sometine in the last 20 years and lost and I
need then to finish up a simple first person documetary by one of the pilots.

I'm looking for:
1) Armand Peterson, first exec from May 1942 to hos loss on his first mission
July 1st 1943.A standing outdoor portrait.

2) Col Jim Stone from about Aug 1943. Stepping into ot out of a cockpit.
3) Jene Roberts, "The Spokane Chief", from about the same time (one of the
78th's aces), seated in his plane.
4) Harry Dayhuff standing in front of the prop of his P47.

I can post very low quality images from a VHS that shows the photos that are
missing. I'm looking for ideas on where to find originals. These were all AAC
portraits for records and press releases and all take place at Duxford.
