The 777 Lumina appeared in the Buck catalog from 2005-2007 and came in 3 translucent colors, smoke, blue and red. The blade steel is listed as 420HC. You will need 2-CR2032 batteries to get the LED flashlight back to full power. It is programmed for 4 levels of light output - high beam, medium beam, low beam and flash.
I like the looks of this model and need to add one to the collection.
