I haven't seen these gents before, sorry - one DOES look familiar to me, but I'm not sure that it's the person I think it is.
Lemme check around and see if I can find you a match facially. I think you might be right on the first one.
If you don't get much of an answer here, you can always try
http://www.luftwaffe-experten.org/forums/index.php - the LEMB board or axishistory.org.
They're pretty good for ID'ing pictures.
And great score on the eBay find, BTW. Must have made a great early Christmas gift for you!
