HI! I am the production supervisor at Calstar. The rod you have in your picture is one we made specially for some customer. You can see that with the abbreviated label that says only GF without the GR or DH designation. I can't tell you who we made this rod for but it was made to their specification as a marlin casting rod. It is a genuine Calstar rod built at our factory.
Uh, sorry but when we make a non standard rod, I have to cut the labels so they are not mistaken for our cataloged factory rods. Sometimes I have to lay in a different line rating or blank number and I am stripping in the different label pieces. Unfortunately you received erroneous information.
