QR Code Link to This Post
It was in need of a service and was completed and is now working great.
Video is for your viewing.
It does have a few minor cosmetic imperfections but overall it is in very nice condition.
These are very rare and this is the top of the line.
For local pickup only. Will demo for the new owner.
