Cortland Line Company
Makers of the ProCrest and FR2000 flyrods. Eventually, they bought out Diamondback, including the Dglass line.
Leon Chandler Signature rods
Blanks spigot ferrule built by fisher, downlock alluminum reel seat with rose insert, and I remember someone on the forum saying that they were hand signed by leon.
I own a 9' 8/9 wt and it is a great light salmon steelhead rod. Light in the hand for that length and wt of glass.
I do not know who built the blanks but they came early on with metal ferrules and later with a lighter glass (color too) with glass ferrules.
