Badger, thanks again for the extra pics, they are invaluable!
So we have the PCB and something pretty dang close for the laser pointer/flashing wand thing. Lets see if we can nail down the calculator? I've found some that are similar, but not the specific scientific calculator yet.
Also, the clamps holding on the orange rod on should be easily found (especially if there's a number on them, which there appears to be). They look like padded clamps with the rubber removed, I am guessing about 3/8-1/2".
The battery pack could be more tricky with only the letters "BL" visible.
Similar batteries...some look to be the same cell size, but too many cells.
The case looks to be some sort of metal (aluminum) case, which is quite an odd shape...might be beyond finding, but a nice replica could probably be sculpted and cast.
