The model is called the Mirage, in the Leisure Series. The first part of the serial number tells us the equipment pack which was used from 2000 to 2002. The last part of the serial number tells the month, year, and the sequential number that the spa was produced in that month. I believe it's a 2001, I always have trouble reading these old serial numbers. From 2000 to 2002 all Mirage models were the same size, so if your cover company has a template for a 2000 to 2002 Mirage you should be good. This particular model has changed sizes 3 or 4 times, so it's important to give them those years. Not sure who your cover supplier is, SunStar will definitely have this template. Looks like a nice find!
