WWII German Army M43 Tunic Collar and Sleeve Shapes

Comparison photos showing 5 unaltered original enlisted issue wool Heer M43 tunics. This first photo shows the collar and lapel shape. To take these photos I unbuttoned the top button and held the collar open as if it were pressed open. Many differences are readily apparent. Sometimes the collar extends past the lapel, sometimes the lapel is wider than the collar. The relative widths of the collar and the angles of the various shapes are very visibly different.

This photo shows the sleeve shapes. I laid the sleeves as flat as I could to show the shape. They are not all the same. There is a persistent reenactor legend about "curved sleeves." I'm not sure what is meant by that- but see for yourself.
