Ayres Cirencester line marker

This missing the pan and the belt and has a replacement handle, but is clearly a companion for the Cavendish.  I doubt if Ayres, who were sports equipment makers, actually maunfactured these; they probably had them made by someone like Follows & Bate.  Does anyone have a marker of this type with a possible manufacturer's name?
