Hello,
As something of a Jagdpanther enthusiast I'd like to call attention to some possible ahistorical elements of JJ's Jagdpanther. The model they have doesn't have any period photographic evidence to support it (at least not that I have seen, and I have requested some from JJ).
JJ's current prototype version has a G1 rear deck but a G2 late bolted mantlet opening. To be a true late Jagdpanther, hence a G2, there would need to be consistency, which means that the rear deck would need to be like that on a Panther G (with the engine intake heater and a few more adjusted details). To be a true G1 version there would be no bolted mantlet opening. I hope that I am wrong about all this--and perhaps someone can correct me--but for some reason modeling companies seem to struggle with depicting accurate Jagdpanthers.
Cheers!
