Somewhere amongst my ‘stored’ worldly possessions, I have three such hooks (19/0) that I kept as souvenirs from my days as a marine biologist for the state, back in the mid-late 1950’s. They were hand-forged and came complete with either 3 or 4 feet of chain leader with a bull-snap attached. We used them for sharks. The line used was 3/8 inch hard-laid manilla rope with a thimble braided into one end. We ‘hand-line’ fished them. Sharks always followed the boat to feed on the by-catch from our trawling samples. We would put a fish or two on the hook and throw it overboard whenever we saw a shark near the boat and ‘hang-on’! Once hooked, the line would be run through a snatch-block hanging from the rigging and then a couple of loops of line would be wrapped around the cathead on the winch and tension would then be applied to the standing end of the line. You can rest assured that the winch is a very satisfactory single-action saltwater reel with an outstanding drag system for this type of fishing!
You are probably wondering ‘why were they doing this’! Members of the fish family Sciaenidae (trout, redfish, croaker, black drum, etc.) frequently have the larval stage of a tapeworm in their flesh making them unacceptable in the commercial market that existed at the time. Black drum are the most frequently affected species, with speckled trout and redfish right behind them. Given the importance of these three species to the, then, commercial, as well as the sport, fishery, we were trying to establish the definitive host (adult worm host) for this particular tapeworm. We were able to ascertain that the adult is found in the gut of sharks, as suspected.
I have long threatened to get an old-fashioned cotton mop, remove the handle from it, and attach the mop behind the eye of the hook in the fashion of a “Hootie”, which was THE fly for Spanish Mackeral in that area of the coast at that time. I have not followed through for lack of a place in my tying area to display it. A hook that is close to 12 inches long, with a 3-foot chain leader, and 3-inch bull-snap ( a heavy duty swivel snap) does require quite a bit of room to properly display.
The Hootie was nothing more than white nylon cord (several strands, doubled around the tying thread and tied to the hook behind the eye, and tied off. The strands extended just past the hook bend, and were teased apart with a coarse comb, leaving just a thread skirt around the hook. They were deadly on schooling Spanish Mackeral when trolled behind the boat.
Given the complete assembly, $45.00 does not seem unreasonable for such a hook. That is peanuts when compared to the price of the " rod, reel, and line" required to fish it.
