Ding ding ding we have a winner!
I was missing an orange ME45 for my collection (Desert Panzer, Urban Panzer, Arctic Panzer, and now Cyber Panzer), and when I saw this proto for sale, even though it came without battery cover or battery, I couldn't resist.
And yes, it has the altimeter, the barometer, the thermometer, and the polyphonic ringtones. It does lack a file explorer, the sent SMS menu item doesn't work, and accessing the calendar makes it go "beep" and turn off, but it's still a rare item. And it's mine, now!
Now, which avatar shall I use for the next 24 hours? (not that much people will notice it, though )
