P1839 Forage Cap!

My first attempt at a pattern of 1839 US Army forage cap.  The body is made of dark blue wool broadcloth, interfaced with heavy hemp canvas, and lined with brown cotton sateen.  The crown is welted and padded with wool batting.  The visor is painted and varnished using period recipes.  It is attached with a leather welt, per originals.  The varnished leather chinstrap is attached with two flat brass buttons.  The fold-down cape is tied with black silk ribbons, and attaches with two hand sewn buttonholes.  Still looking for a source for the correct buttons.
