There are a few other sets with religous figures. In the viking era Orion included a monk in their viking set (although about to be killed by a viking trying to steal his cross) and Stretlets included a priest in their Caroliginians I believe. The Pegasus South Western Mission People has about half a dozen monks, while the Imex Pilgrims has a Preacher.
If you are rich enough to buy the Zvedza battle sets then sometimes they have a unique figure. In their Teutonics/Livonians against Russians you get both a Catholic and a Greek Orthodox priest. I have neither since I already owned the rest of the figures and wasn't prepared to buy loads more just for the specials.
Strangely there are no figures of Nuns although these up to the present day can be found working in hospitals.
Hi Andreas,yes peasants for sebastopol defences perhaps manning carts and filling sandbags (a generic figure could be used with many sets,CW Russian navy almost gets there ).some shameful "body & warehouse looters" which i believe happened alot more than is historically recorded.
