Ken,
Always enjoy seeing pictures, as the old saying goes "are worth a thousand words", thanks so much for posting these. There are three names you have listed from the pictures that I have found in the Company A records that I have:
PFC Roy T. Kollman
PVT John F. Guthrie Westchester County, New York
PVT Floyd Savill Hancock County, Indiana
Here are three photos from my grandfather's collection at a POW camp. The first two are not labeled, in each my grandfather is on the right with an unidentified soldier on the left.
The last one is a photo of just him, I just discovered this morning it had writing on the back, awesome!
Apparently the 292nd not only built POW camps but helped in the guarding of the prisoners as well. My grandfather's letters to home make several references to guarding German prisoners. Have a good one everybody and keep those pictures coming!

Randy,
Great addition to our group. Makes you want to figure out who those other guys are? Maybe someday soon, my friend. I was so happy with the prints that I had to call Hampton House and let them know. Laura was great! The one thing that struck me as a little unusual was that the "C" Company photo that you acquired had labeling added when developing or printing, but "A" Company did not. I thought that was kind of an odd inconsistency. Did Lisa ever mention if her relative said much about how he came to get the original print? Also, did your grandfather send many letters back after Germany surrendered? My grandfather sent a leter with a list of when certain things occurred after censorship was lifted following Germany's surrender. If your grandfather sent letters later I just wondered without the fear of censorship if he talked somewhat more about what he was experiencing during his deployment?
More questions sometimes than answers, but we'll keep on striving for the answers.
