I have had this 'photo stored so long that I forget its exact provenance - I hope it is not a repost.  I think it was captioned as "Das Reich" panthers in action in 1944.  What interested me about it in particular is that these panthers are operating with open commander's hatches - a strong indication that this is "live combat" rather than any sort of re-enactment.  Any comments ?  JR.

Panthers in action.

Inspection

Here is the original picture of the Prototype leFH 18/2 auf Fgst PzKpfw II(Sf) take in 1942 that was posted previously as being a Wespe AA gun taken during the siege of Budapest 1944. 

Compare the 2 and you can see where the Budapest photo has been altered by photoshop or similar program.
