Four of these were laying in a dlispay case. Two were in awful shape, the other two were like this. There was also a TP-T in nice shape and a couple of dummys.

Cool! I always try and pick up nice pieces of ordnance when I can. My son likes it. Good find.

Those are in nice condition, congrats 

I would be very warry with the HE one, it looks to be live, and if it is would be illegal. There have been a bunch of live HE 20mm found in recent years, the BATF have been hunting down where they have been coming from. An auction house a few years ago sold a bunch to unknowing buyers and got in some trouble, as they advertised them as inert when they were obviously not like these rounds. Good luck. 

Nice find they look to be in pretty good condition. I’ve bought some unique pieces when I’m out and about I check those little “antique” shop or those shops that have a little of this and a little of that.
