It would help if you posted the inside mouth diameter (hole at the top), case length and rim diameter (the width across the base where the markings are).

PS I am 18 now, I started collecting when I was about 13. My collection wasn't anything like yours when I was 13.
Not sure about this one but it shares the ridged rim with the Naval A/S Hedgehog launching case, only its a bit to long.
Anyone add to this?

Best Weasel.
