I have two possible general elements. The Gen Bd above features Italeri/Zvezda Gauls. The horn player model originally had funny furry pants and boots, so I glued his torso onto the legs of another model. The other general element is Cavalry (seen in the rear of the top photo)
Hat Celtic cavalry with one round shield converted to a hexagonal body shield. It's not my best paint work. The models are coated in Elmer's Glue (white PVA glue) to prevent chipping. It works great, but it's a bit shiny (I now use Windosr & Newton's acrylic Matte Varnish). The army was painted in 2001 or thereabouts. I almost want to do the whole thing over again! There have been a number of new 1/72 Hat Celtic releases since then, so it would be nice to include these. And I would like to have an army painted to my current standards. Maybe I'll do the Ancient British (same models, but a different army) and imperial Romans.
