Without pictures, no. Here goes the basics- head cases were metal stamped , eg, 75mm , M18 , BB, 1942 at the plant. That would signify a 1942 M18 75mm case made by company " BB". WHEN it was loaded at the factory, with either AP, HE, etc,...it was INK stamped on the head case over the factory metal engraved basic case info, with the powder lot number,completed projectile type. Same with a projectile. The loaded projectile was yellow INK or laquer marked ( HE) with type ( M62A1, explosive filler type ( TNT, Comp B etc,) , ( G) gun or ( H) howitzer type ( 75MM G- 75mm gun, tank----75MM H, 75mm howitzer)...that is the basics, and that is why original ink marked complete rounds are rarer and very desirable by collectors. I have a few original examples but this site will not load my pictures. Basically, The black ink markings on the case head and yellow HE ( or white ink markings - inert or AP) on the projectile were applied WHEN loaded at the factory. You will not see many as bubba likes a shiny case and polishes off the ink marking from the used case or the case was never loaded. Same with the projectile but finding an original yellow ink marked HE projo is rare as it obviously was downloaded at one time...you can find original AP ink marked projos as they were usually just large metal slugs...last word, beware, many collectors " re- ink" projos as they look nicer in original, issued colors. Make sense? Lastly, I stated general facts, there are differences and variations (as in the rarer US 3" G rounds with steel cases).
