If Im not mistaken, that would be a Panther model G on the account of the side skirts. The Model D version was not equipped with the side skirts in its production time. Other than that, its a very good detailed piece of work!
Hi all and thank you so much for your kind comments
MEC518: the Schürzen (massive or grated iron skirts) were a standard addon to all the Panther series (D&G) from April 1943 until the end of the war. The mount type portrayed on my render is an early version changed in the Ausf.G series for an improved design. I will recommend you an excelent webpage about Panther tanks... but sorry, it's on Spanish Language !
