Because the secondary functions are blue and not yellow, the front case is not from an 83-V or an 87-V. I'm guessing it's an 87
If I remember correctly, the 87-V has the labeled surround, so the only way it could be an 87-V is if someone changed the LCD surround and front case. (windows are welded to the front case. and aren't eaisily replaced.)
The button assy is from an original 87 or a cat II 87. (It doesn't have the "sun" on the backlight button that the -III has)
My guess it's an 87 I or II (none were labeled II, that's just the second, category rated version) with a different front case on it. The blank LCD surround is intended for use with a printed window, while a blank windowed front case was intended to be used with a labeled surround. In any case, the LCD surround and case don't match. on this meter.
I'd say it's a genuine Fluke SOMETHING, but since parts have been mixed and matched, anything's possible. My guess is simply the most probable.
EDIT: That's what I get for not reading ALL the replies first. I see RC came to the same conclusion. (I agree with his recommendation about buying)
