hello Sultanbev
why do'nt you have a look at Irregular Miniatures 28mm Italian Wars of Indipendance/FPW range..they are not in plastic but the list include a sapper type with choice of tool (pick, axe) for many troop types and with different uniforms all belonging to similary dressed 19 C types. ..even a Pontifical Zouave sapper that could be easily transformed in a Turkish infantryman..i suppose that swapping heads should prove easier than converting arms..about the aprons probably some or all the figures are'nt equipped with it but, according to my knowledge, majority of armies in campaign dress (as the Neapolitans,Piedmontese, Austrians or Pontificals for example) did'nt wear it on campaign uniform.
