Yes, That is indeed the beast that I was inquiring about. I once told someone on another forum that I no longer frequent that there was a modern Sturmgeshutz based on the M113 hull. He argued with me on why this was not possible. He continued to argue the point even after I presented him with the links to these same images. He was still refusing to acknowledge that I was right in calling this a SturmGeschutz which for all intents and purposes, the M113 Assault Gun armed with the 105mm Howizter is a SturmGeschutz. I also thought it was quite ironic that the prototype was painted up in what almost looks like the old yellow used by the Werhmacht before camouflage became a requirement.
