It was at Dinnington Colliery Junction and is clearly paired with a GCR pegger and bell - but I suspect the non-pegger dates from before the GCR, so maybe MS&L? On the other hand, the box was Great Central, Great Northern, Lancashire & Yorkshire & North Eastern Joint so it could have come from almost anywhere . . .
But I am wondering if it might not have always been here, but was provided at some point when the block shelf was re-arranged, leaving no space for the width of a normal non-pegger.
Sorry about the quality but it is actually cropped from the corner of a general view of the frame.
