Wish I could post a picture

Went to the beach, and found some very old munitions. One of them was completely in-tact, not used. They look like automatic weapon munitions, perhaps from WW2. One has the inscription L. C. 42, the other F. A. 41. The numbers and letters are at the base of the munitions. They are approx. 4" long, and vary in diameter from 1/2" to 5/8". Does anyone have any expertise in this area, and is there any value to these, or approx. era they were manufactured. Thanks for the help.

but you may want to contact your nearest Military facility and see what they say about those. You never know what you may have.
