Instead of went through all those skinning and copy, paste, why don't you increase the amount of man in the desc_unit to a larger one?
this isnt wot he was asking(at least i dont think)
he wanted the peasant unit sizes to grow as the city grew(i think)

BTW Richard you know what the max one can increase the unit to? I mean from 60-XX
richard answered this question already for u the max unit size in descr_units.txt is 60 this is then doubled and then double again depeding on the unit sizes u have selected in the options.

there would be no need to copy and paste skins in my solution. all u need to do is copy and paste the peasant entries in the relevant text documents and renaming the unit. It would use the same modles, and skins.
