Digger70PA, Let's Get Back in the Huddle on This One
Depending on the military contractor, some of the standard Enlisted eagle buttons were gold guilted. Many of the Eagle I's, A', C's, D's R's are the Enlisted style 2-piece buttons and were also gold guilted. Back in the day, we dug a fair number of gold guilted Enlisted Eagle buttons in CW camps here in Virginia. Eagle two-piece buttons, gold guilted or not, were generally for Enlisted personnel.
The three-piece button, known as the Officer Staff button were used by the Officers. Every one I ever dug or have seen was gold guilted.
I recon when times were tight, they wore anything that would hold the jacket closed.
BTW, the Museum of the Confederacy in Richmond, Virginia is in possession of numerous documented Confederate Frocks, Vests and Shell Jackets that had common enlisted eagle buttons on them. Some the jackets were enlisted and some were officers.
I think we all agree, no matter who wore them, we love to dig em.'
