It's a Sharp 70LE640U. It's not manufactured anymore, but the 70LE650U is. Not sure what the difference in the new model is.
When I went shopping for this, I did it local at a regional mom and pop shop. I must have looked at 20 TV's in their show room and this Sharp TV stood out from the rest. If I recall, the pric was $2,200. About a year after it was installed, I put a Chromecast on it and that is how it gets used nowadays. The workstation hooked set up for this TV just sits idle now.
