I feel like I have seen something like this before but I cant name it...

The fins look similar to the .50 short range rounds so perhaps they did the same for cannon ammo?

Doesn't look fired, looks dispensed, air dropped. The design looks vaguely familiar, but it is not clicking. Not near my library, so cannot do any looking for a week or so. Sorry. Let us know if you hear anything.

I don't know what it is, but looks very similar to some flechettes I saw in Iraq that came from clusters that we destroyed. Lots of various countries' items in the pit, so I had no idea what came out of what cluster. Of course, those flechettes were less than 1/2 inch in diameter, not near as large as this, but the design was very similar. Just a thought....

If I recall correctly the Czechs had a couple of bomblets that size and shape, maybe pre-WWII. Longer fins, but that may be what I am thinking of. Any Czech members out there with photos? I've got pics at home, next week.

Vaguely reminiscent of an incendiary, but way to small I think. Certainly looks air dropped. I have no idea.
