Hi Keith, again. the sudan figures, from the top are; Emir, Beja tribesman (left in the second row as you look at the photograph), Hadendoha & a soldier of the 21st Lancers. This latter figure appears to have the wrong lance but the tribesman in the top right might be holding the lancer's lance; there should be a furled pennant around the lance top, probably just a case of swapping the lances over. The Napoleonic is probably a French Garde Grenadier Sapeur.
Good luck with the Ebay!
