Going a bit overboard on Gallic conversions...

 

Might get back to the Romans eventually.. original figure in the centre, officer and spear/shield cavalryman conversions - gives all the figures for an interesting cavalry unit...

The cavalry figure mounted on bases as infantry (just pointed the left foot forward for the standard bearer, cut down standard and hammered flat for officer. Two other standard bearer conversions in centre. 

Lousy picture - spear/shield cavalryman given a standard.

This lot, together with other Gallic conversions, make an army more viable. Meanwhile, all the figures with bison headresses give an interesting option - a fantasy army of Northern Barbarians...
