Several small-caliber cannon rounds in my collection have either the letter “K” or “G” printed on the projectile along with the caliber. For example:
35x228mm HE, Dutch (made for Germany??):
CTG DM 11
27x145mm solid aluminum dummy, German:
20x139mm break-up, Dutch (made for Germany??):
What do the letters “K” and “G” mean after the caliber? Is this strictly a German marking? Am I correct in thinking that the rounds with Dutch manufacturers are made for Germany, given that they have “DM” model numbers?
Thanks in advance for any input!
