I don’t know about pictures, try a google search, but the N. Koreans/Chinese knocked out lots of them. The Chinese T-34 could slice through them like butter. As for the model, nothing needs to be chnaged to make it a Korean War tank. Because it was only 5 years after WWII, the equipment was generally the same.
I’m not familiar with your kit, but if it includes the single pin track you may want to pick up a set of double pin track for it. I believe most Shermans were upgraded to that track by the time they were sent to Korea.
