Based on our history of the Performer(s), the colors offered in Gen 1 include Black, Red, Red Mist, Dark Green, Dark Blue, Plum, and Grey. No Irish Green or Bright Green or whatever. If fact, none of the Perf's have ever been issued in other that Forest Green with the exception of the C&B Grass Green.
You got a knock-off, one-of-a-kind, Weber "special" green SSP. You better hang on to that baby. Congrat's !!!
