That is a NAMM 100th anniversary Stingray. I believe the color is Inca Silver. They come up every-so-often on ebay. Oli@bass, one of our members on your side of the pond, has two of them. One of them was for sale recently, but I think he still has it. There were only 100 made.
I should have snagged the NAMM 100th at my local dealer when they first came out...I just didn't have the cash...same with the Onyx Sterling they had when it was new
