Shakespeare Sigma x2 Beta x2 and Angling Pursuit x1

Shakespeare Sigma x2 Beta x2 and Angling Pursuit x1 all work . The only reel that has an issue is the Sigma 40 FS the locking mechanism on the back wind is not working,something simple like the pin has come out but I cannot say for sure. All reels are in good condition but the plastics are fading on most apart from the Sigma FS but not excessively. All have line on one or two need topping up.Reels Are : Beta 30RD Beta 40RD Angling Pursuit DZ40R Sigma 35FD Sigma 40FS.
