Me...I'd buy one of these cheap $16 holsters from DGW, pull it apart and go from there.
HL0231 1860 ARMY MODEL HOLSTER R/H
Left hand type holster worn on the right side according to military regulations. Nice quality leather, muzzle end sewed round with brass stud closure for flap. Our BL0301 belt will fit this holster.
