M4A3E8 Sherman Tank "Easy 8" (1/35 scale by tamiya). See full build and diorama pictures here: http://www.sportsattic2.com/Military/SAmilitarymodels.htm
This was my 2nd overall build and first diorama. Learned alot, will definitely do some things different in next project. Diorama does not reflect any specific time period but the entire project was used to practice tank building and diorama skills. Will be better next time! Enjoy!
