Brad, John Eden has some Cavalry show, but as painted figures, be he also says they are available as casting.
He has both Horse Grenadiers and Dragoons, and here are some images.
John
Yes, in the time since we last posted to this thread, John started using an eBay store pretty heavily. Since then, I've picked up a lot of castings from John, particularly civilians by Sanderson and others, some for my 18-century collection and some for my Imperial German collection. He also has a stash of Puchala kits and I've taken some of those off his hands. I still haven't gotten around to getting any of the Rose cavalry figures yet, though.
Prost!
Brad
