http://imgur.com/jAjHH8P I need help understanding what the markings on this shell mean. If there is a better place to ask this question please direct me. Any and all info would be greatly appreciated.
"75 DE C" means the shell is for a "75 mm De Campagne", the ubiquitous Matériel de 75mm Mle 1897 Field Gun used in WWI and WWI by the French and US and a whole bunch of other countries.
"PD Ps" is the Parc d'Artillerie de Paris, the manufacturer
"1149 L 17" means Lot 1149, in the year 1917
