Well this won't help much except to get somebody else thinking or digging out some stuff. I couldn't find my good camera, so the cell phone had to do. Looks kind of vintage, just like the rod, an HMG 7 1/2' for 6. HMG stood for "high modulus graphite," that I know. The ferrule is sleeve type.
The rest is kind of fuzzy. especially since I never paid much attention to graphite rods other than Fisher after 1980. I think the modulus ("stiffness") was a few thousand more than the first graphite scrims used, let's say 38000 as opposed to 33000--something like that. In other words, although they can be thought of as "soft" graphite by today's norms, they were "stiff" graphite in their time, and actually started the trend towards "stiffer" (higher modulus) graphite.
You can see the tube. I never use tubes routinely, and I threw the sock away. Together, these too things ruin a lot of rods--exactly what happened to this one in the previous owner's hands, or, actually, sitting in a damp space in a damp sock in a tube. Sometimes it got rained on, sunned and dried sitting on a porch or laid in a boat--"weathered," I call it. I watched it deteriorate over 20 years or more, right along with the owner. Then he died and his widow gave it to me.
Well I don't remember the original colors of the wraps or color tone of the blank. I thought it was gray, but it looks kind of reddish now. I quick refinished it one night with what fell to hand, probably a spar varnish with an amber tone. So that is no help.
But it is a darned nice little rod for graphite.
