Yep id say the one on right held stripper clips or modern clips, i did not blow it up. I definitly know the right holds a shovel, id say its vietnam era to maybe the 90's. I work on military bases and find these from time to time, modern ones i think at least some of them are in a rubber material. I know this cause the only complete one i have found in case and all had a rubber case that it was in. I keep it in my 4wd truck behind the seat in case i need and emergency shovel.
