Sure
Here are a couple of holsters from
www.ima-usa.com. or maybe it was What Price Glory

Both are paired with original guns, though in remarkable condition the guns do have honest patina.
So, to display with holsters at the museum, the newly made holsters needed some attention to detail.
Chuck instructed me to use acetone and 0000 steel wool and judicially rub the surfaces to the look you like.
I also use rubbing alcohol and burlap or mildest scotch guard.
Currently, I have some prefinished pebble grain and I use the alcohol and paper shop towels to
to achieve a patina before I will sew into a Replica WW1 holster for German side arm.
