I've been comparing the new ones to my vintage gun and can't really see a solid, definitive difference between them. A color scheme that's not red and black indicates vintage, but there's no evidence that red and black wasn't also used in the 1950s. So there's no way to tell if a new one is really an old one, or vice versa.
However, I think I finally found something significant. It's tiny, it's hidden, and I almost missed it.If you look at this enhanced close up, you'll see what looks like a small holdover from the molding process, a tiny, circular indentation common to many plastic toys.

However, imagine my surprise when I discovered that it's
not something molded into the plastic, but is in fact a
small plug that's removable. Doing so reveals a hole through the lower fin, perfect for a piece of string or some sort of a lanyard. I'm convinced this is what it's for because I only discovered it when I noticed some small threads -- really small, really fine -- sticking out of it. (I originally thought they were thin, string-like, plastic remainders -- again, imperfections in the molding process.)
I'm betting the modern versions of the gun do not have this plug. And if not, that's a pretty solid "tell."
I'll post more -- and better -- photos of it tonight.
I also wonder if the
internal spring and
washer are different on the vintage versions. These guns are designed to pop open for easy cleaning and oiling (after all, you're firing bits of vegetable!), so it's not hard to check. I glanced at it when the toy first arrived, and the washer seems to be made out of thin leather or something, not rubber. But I only took a quick look, so I could be completely wrong. Again, I'll check again tonight and post some photos.
Finally, I just noticed that Astrogonza's photo shows a
small ridge on the bottom of the red part of the handle. Mine doesn't appear to have this -- but it's showing the wrong side, so I could be wrong. I'll need to check again when I get home. Astrogonza, does yours have this ridge on the red part of the handle on both sides?
