The buttons appear to be the flat engineers buttons, but hard to tell. The belt buckle is a Virginia buckle with the indian standing. The case has a patriotic eagle , with flag in it's beak and 33 stars around the edge. At the beginning of the Civil War , till 1863 there were only forty six engineers all graduates as required from WEST POINT , the confederate started with only seven engineers. This engineer I'm sure the engineering officer, could be id with some work, due to the small amount of WEST POINT grads.
