I was gifted a bag of mixed climbing gear and one (well technically 2) of the things in the bag was was these 2 belay plates. I have never seen anything quite like these before, no markings, and too thin for my single rope, half ropes just about squeeze in. Retaining loop is solid.
Anyone seen them before, know brand etc? I would like to say there is no way I would use it, but I clearly am just to see how awful the action is (I will take sensible precautions in case of failure).
