Quick reply...

All front parts assembled? Dream on, you are more likely to find a grey prototype N950, all parts assembled, than just front parts of it assembled.

LCD panel? Looks virtually identical to the "usual black" N950's LCD panel. To be sure, read the red letters, and look them up, until you figure out the "part number" or something of the LCD panel.

Most likely, you will only find Chinese sellers. For N950 LCD screen I found only http://www.mobilephone-spares.com/No...D-Display.html
