Even though it may be a new photo of tricorder with bottom door open, I can assure you that I have seen similar photos of the HMS replica photographed that way. It simply looks too polished to be a toy.
Again, I am NOT knocking Diamond or AA or whoever is actually manufacturing the toy, but it will be a toy, and I think if you are looking forward to getting this, you should adjust your expectations to it being 99.9% plastic -- any metal parts would truly be a bonus.
Still, even for $50, an all-plastic actual-scale accurate replica of the tricorder will be a FIRST at this price -- or even as a toy, as every other toy that has been made of this prop has either been grossly inaccurate or too small.
I'll be looking forward to this.
Here's another neat idea -- if MEDICAL version came with McCoy's scanner (the one we are most familiar with and is most often seen in series) and the SCIENCE version came with the larger scanner which can be seen in beginning of NAKED TIME and sporadically throughout series -- maybe by Kirk in GARY SEVEN episode, too. It's similar to McCoy's scanner, but appears to be a little larger, grip material is different, and there is a little hole on top through which one could see different colors, if I recall. It did NOT have the spinning mechanism seen through clear upper chamber like McCoy's had.
