Russelure has been around for some time. About 1982 or so, I remember they were going out of business and I bought all I could find. I think I still have 25 or more from the original manufacture in their original package. Years went by, and somebody bought the rights to russelure. I belive this is correct, but I might be wrong.
When they came back on the market, the old timers said they weren't the same. Did not run as true as the old ones and the aluminum was thinner. Of course, this could have been a rumor. I'll go buy a new one and compare it to the ones made in the late 70s. They do work. Theres no doubt about it. Pull them close to the transom. Watch out when retreiving them as they will pop out of the water and come right at your face. I had to pull those trebles out of at least three people who did not bring them in properly. Put the boat in neutral and retrieve slowly when retreiving them.
