Caxton line marker

Caxton line marker with internal-tooth chain drive  (like the first Silens Messors).  There should be a rod passing through the hole in the handle crossbar, with a wood handgrip, attached to the hinged section of the channel connecting the inside wheel with the marker wheel. I was going to replace this but for the moment cannot lay my hands on a picture of the original (I know I have at least one somewhere). I offer it now as is, for comparison with Andrew Grout's, which clearly has some features in common.
