I recently got a Bespin blaster whose plastic is far more translucent than I've ever seen before. I'm aware that some of the early 21 figures came with weapons that had a translucent flare along the edges, most notably Chewbacca's bowcaster, but I've not heard anything about a weapon whose translucence goes deep. And until doing research on the topic I had not heard of any ESB-era weapons having the translucent flare, but apparently it was the case with 31-back figures.
But now I have this Bespin blaster who is translucent for the majority of it's bottom half and a pinch up top. I don't believe it to be a repro as it does not have any of the telltale signs of a repro, when away from a concentrated light source it matches the color of other blasters, it is molded accordingly, and the drop sound is ok.
So I'm curious to know what I have here, is this a blaster that just had a bad piece of plastic during the molding process 25 years ago? Is this something more commonly found than I'm aware of?
Here's a comparison pic with a regular Bespin blaster, the translucent one is on top.

Any insight would be appreciated, thanks!
