I look at it from one possibility for him...I had more than one of a few things and only have room for so many. I sold my extras even though they were hard to find. Now I have more and the sales paid for the new ones. If he's offering just an 8.8CM projectile, that's not much in my eyes, the whole round would be different. They just have a huge rep from history. Maybe you can get him to disclose exactly what this one is. I got a couple of my big projectiles by accident, one by a clear misidentification.
