I got it through “It’s a Wrap” but it was mis-listed as ENT “Sample Jar Lot W/Case” here is the listing: http://startrekpropcollector.com/trekauctions/item.pl?i=5062
In addition to the wrong description, It also said that only one of the 4 was removable but in fact all 4 are removable and functional. They all had batteries in them and all lit up when I got it. I was thrilled because it had been listed before and I had bid over $1000 dollars but the auction ended early for some reason but was relisted. I picked them up for under $300 bucks, lol. I did give you some bad information before. It seems that all of them have an outlet plug for an AC adapter and one of them has 2 plugs; one at the top and one at the bottom. Also, they all have provision for a tripod mount on the bottom.
I took about 30 pix so I was thinking I would just start a new thread devoted specifically to the lamp since this thread is about the case.
In the listing you posted about about the lamps there are a few small differences between that one and the ones I have. First, it is missing one of the brass square tubes on the side (the one without the wires inside). The one without the wire can easily fall off and in fact one of mine has it cemented to the glass. This one obviously had fallen off and was lost. You can see the tongue where it was connected at one time. Also, the bottom does have the cover on it so you can see where the AC plug is cut in on the upper RH side in the top photo.
