I haven't seen a picture of the original "real" gourd for Addy anywhere here so this is mine:
I really like that it is obviously the real thing. The inside of the neck shows where it was scraped out, and the outside is imperfectly polished, but that makes it look authentic.
On the con side, it is incredibly light. I'll bet it weighs less than 1/2 ounce, and it feels like you could crush it without trying too hard. Maybe that's another reason they switched to plastic gourds.
I'm not clear on whether the plastic gourds ever came with stoppers. I think I remember that the original paperwork suggested using a bit of cloth or a clump of grass as a stopper--just as Addy might have done.
