Don't know if anyone can help me with this issue, but here goes.
I have a copy of "Panzer" by Claes Sundin, a book of profiles which includes on p111 a side view of a Jagdpanther supposedly of "Hohenstaufen" (9 SS Panzer) which was crewed by the post war German novelist Gunther Grass. It shows this as a G1 version in Terschen (Deein) Czechoslovakia, with a Dunkelgelb and Dark Green striped finish and no codes. This would have to be in 1945, following on from "Spring Awakening".
I've searched the internet unsuccessfully for any trace of a picture that this profile could have been based on, nor can I find it in my references on Panthers and Jagdpanthers. I don't have it in the unit history either, although the division did have 8 Jagdpanthers as late as March 1945. To me it seems unlikely to be a G1 this late, especially since "Hohenstaufen" didn't have any of this vehicle until at earliest November 1944 when it was being rebuilt for the Ardennes after fighting in Normandy and Arnhem (at Arnhem, "Hohenstaufen" had no tanks of any type), by which time all the major upgrades had been done.
Would a G1 have the early type internal mantlet? If so, I've definitely bought the wrong kit to make this vehicle, as I have a Tamiya Late Type (G2) with bolted external mantlet and crew heater on the rear deck.
Gunter Grass published a short account of his wartime experiences near the end of his life. He was a teenage draftee assigned to the Waffen SS as an infantryman (they had run out of fanatical Nazi "supermen" by the war's final year, and were conscripting from the same pool of high school students as the other services).
He completed basic training in 1945, just in time for the collapse of the front, and was swept up in a disorganized retreat. He reports seeing a Jagdpanther, but not crewing one. He threw away his SS jacket and acquired an Army tunic before surrendering, as he knew how hated the SS were. His own views were leftist, and he kept his wartime association with the SS a secret for decades, as it deeply embarrassed him. He finally decided that truth was more important, and published his account.
