Hi Everone, just been down to a battle site that was fought in 1863. Found this item but not to sure of age or use. Had a crimson filling that I have taken out, Does cordite turn crimson with age?? Dimensions are 40mm long and 12mm Diameter. End of cartridge reads MED RED. Any Ideas?? Hope the pictures help, best I could do. You comments will be appreciated. Cheers
