It is interesting to note that the photos posted on that other site were posted by an “anonomyous time traveler” some time back. It fits the exact description John has give us of his machine. Therefore, based on his discription alone, I would say he is the one that posted the pictures. If he didn’t post them, then he is using them for the basis of his story.
Regardless of the two supositions above, the device appears to be “authentic” to me. I have some experts looking at the manual and the pictures as well – for obvious reasons, I won’t tell you who because they aren’t aware of this discussion and I don’t intend to tell them about it.
I am extremely familiar with military spec equipment in many forms, more specifically communications systems of various types. I have never seen this particular item (in my time… ) nor anything vaguely resembling it. HOWEVER, it does have the look and feel of a piece of gear produced by a large corporation for the military.
John – in looking closely at this device, I see there is a hand control unit – with some sort of screen on it. I assume this is the computer interface through which the device is programmed (or time settings are made). Is that an accurate assumption? What does the display show you (for instance, does it simply show things like time/date calculations, or radiation [probably wrong word] of the fields from the device?)
Also, there are 16 apparent buttons. I have to assume further that these are multifunction keys (that is you press one for an alt/control function and other buttons have names or labels and perhaps even numerical meanings). Is that also accurate?
