Aye, they are definitely different.
The DC side lenses seem to have the cracks all the way through. On the Noble one, they're quite clearly carved right on the top. I'm not sure how I can fix that part of it, unless I were to have someone cast new lenses and pull these out. Not even sure if I can do that.
In the interim, my husband is building a new light setup to put in it, a cylinder of LED lights that are green and are powered from a similar flashlight housing...it should be much brighter.
I'm going to start wetsanding some of that black finish off so that I can get more of the green to show.
I'll take pix as I go along and probably start a WIP thread somewhere to show the mods.
I'm still hoping to get my hands on a DCD one, so that I can have both in my collection.
