Thought I would bump this 9 year old thread. Just picked up one of these in this weekends EAC sale. It is ex Syd Martin, among a string of other famous collectors. It even came with some nice provenance material. It's an R7. 2nd finest of the 7 known of this variety.
I've got one farthing and one halfpenny which should be enough but I may get another that shows the brass splasher better like this one.
