Kevin,

those are the only 2 photos I have found of those two as well..
HArd to see however it is interesting photo sinnce I belive Dorfmann is wearing bandages.

As For Herbet Frires who is still alive.
you can find him in the "Green Devils" book and the
FJ Knights cross book.

He knocked out 19 Shermans in 2 days with his Panther.
Allowing his FJ kamerads to retreat out of the Cassino sector.

He went from Gefreiter - Oberjager - Leutnant within 6months
and was awared his RRK by Herman Goring himself...

Keep your head's down and your helmet's on!
