Austin-HDH and GBF- back in the silk line era, weight and taper codes, right? An HDH would be a double tapered line, a GBF sounds like a weight forward design, perhaps a bass bug taper. One of my Michigan steelhead/salmon rods was an Orvis Graphite 9 ft- had the detachable FB, alum uplocking reel seat with dual lock rings- believe it was an 8 weight, and I bought it the first year Orvis came out with their 25 year warranty on graphite rods.

I can tell you for a fact they lived up to that. In July 1988, eight of us in the FFF flew into Galgary and fished the Bow river for five days straight- all flies only, all C&R--fantastic- didn't get dark until about 10:30 (2200 hrs.) so we had 12 hours on river time- two to a Lavro drift boat with guide, enough river that we all got to fish a different section each day-

My best fishing pal then had just bought a new Orvis graphite, again, the 25 year warranty. We all took at least three rods and reels up there, usually had one rod rigged for dries or nymphs, the other with ST lines for "spank the bank" with weighted streamers-- Bob had set his new Orvis graphite somewhere near the sockets for the sweep oars, the wind came up and the rod shattered just behind the ferrule- when we got back home he sent it into Orvis, two weeks later he received a brand new one- same model, and Orvis reimbursed him the shipping costs as well- Says a great deal about the "Big O"

FYI- as I was a "tackle junkie" I guess back then, high end reels and rods, here's my arsenal for that trip-- R.L. Winston Std. action graphite -9 foot-3 pc. 7/8 wt. made for me by Glenn Brackett- equipped with early series Ross S-1 saltwater reel with the stainless steel drag and extra spool- Thomas and Thomas 9 foot 2 pc. graphite 6 wt. with Bogdan Trout reel- and Doug Merrick SF Winston split-cane 8 & 1/2 foot 2 pc. one tip 6 wt. with Hardy Perfect 3 & 3/8" dia. reel (I later had Glenn make a matching second identical tip for it- just as I had Bob Sommers made a matching replacement tip for my 7 & 1/2 ft. 5 wt. Young Perfectionist)--

I still have many fotos from that trip-and although I am now "out of the game" I still have many fond memories of times spent on rivers of now remembrances.. All good--
