German WWII Buckles Comparison Pic

Top one is the original Metal Buckle (1st Issue)
Middle one is the 2nd issue when they did away with the metal buckles (Russian also had a metal Buckle) This would incorperate the y webbing black and brown versions.
Bottom one is the last issue as it looks like a totally new mold was made when they changed maufacturers and went thin and cost cutted maybe even moved their stuff from the old sweat shops and into the more favourable manufacturers ?
