I think it is an original M8 without hanger. No signs of there ever being a hanger in the loop or any evidence of stitching at any time. I think I need to first try WD-40, and if that doesn't work, I use the navel jelly to clean the scabbard throat, hilt, and pommel. Probably leave the blade alone. I'll use WD-40 and a brush to clean the leather, then maybe use some Neetsfoot.
