A small sample of original WWII German Army enlisted issue uniform jackets was examined to assess what kind of small buttons were applied at the factory. M36, M40, M42 and M43 jackets were examined, as well as one factory converted Dutch reissued field blouse.
M36, M40, M42 and M43 field blouses each had ten small buttons in addition to the larger pebbled metal front placket and pocket closure buttons. These small buttons measured approximately 14 mm in diameter. Five were used in the collar to affix the collar bind, one closed the internal bandage pocket, and two were used to secure each cuff closure. The following types of buttons were observed in this small sample.

This M40 field blouse had black plastic buttons inside but horn buttons for the cuff closures. Two jackets had different button types for the cuffs as for the buttons inside this garment. It was not possible to determine if these left the factory in this configuration, or if the cuff closure buttons were replaced.
