Vintage Buco Skull Cap – canvas with liner – possible military

Description

This is a Buco skull cap.  I cannot find a comparable to verify that it is military.  It has a label on the inside that says A Buco Sanford Product Joseph Buegeleisen Detroit.  It is a tan canvas,    There are 4 snap adjustments on it and the chin strap is there with the original hook and eye, I believe.

I believe this is military as it came with other military items but I cannot say that for sure.
