Ah, those! Parachute retarded fragmentation bombs. It was the descriptiion of 'cluster bomb' which threw me, as that's a slightly different animal. I honestly don't know if these were in the kit I saw, as the box-art picture was rather small, but they shouldn't be too difficult to convert from a suitably sized 1/48th scale bomb if not in the kit. There were certainly depth charges, which are a similar shape and, next to them, a smaller weapon which might have been para frags, although the pic wasn't very clear.
