Interesting. Was this information published somewhere, or did you talk to the folks involved?
I know that Don Coleman worked for the prop house and he has been very helpful to me in my research on the naiskos, so I don’t want to be ungracious in case this information is coming from him. But I’ve got to say that just having looked at this thing so much in photos, I remain a little skeptical. It even just looks like a different pull from the mold, paint aside, because of the shape around the mouth being a bit deformed compared to the “Chase” version (though it’s hard to say for sure just in pics).
This could very well be a second casting made for Generations, though that’s not what imply in the catalog.
