Over on his Glorious Little Soldiers blog, Andy Copestake has posted some pictures of his recently completed Miniature Figurines 30mm range Chasseurs a Cheval of the French Imperial Guard. From the various comments it is clear not too many people know Minifigs ever made these, and Andy himself says he has never seen any horses (his chasseurs are on Stadden or Willie mounts) or a listing anywhere for this range.
Always willing to help, here is the list, from the 1972/3 catalogue:
No horses here but there is a picture of one in an earlier post (from 2010) here, on which I see Andy had actually left two comments. This is the John Cross review of Miniature Figurines S Range and 30mm figure ranges from Military Modelling Magazine in August 1970. Some at least of the figures had separate arms.
