Ok I would say start of by checking out www.historex-agents.co.uk. On there site do a search for viking and you will get about 5 pages of minis from 1/48th to 120mm. Allso check out dark slave miniatures german warrior and bran celtic legend, both would be great for vikings and can be found in the coolmini shop. I would allso say look at dark sword miniatures as some of them would work well in a fantasy style viking way, they can also be found in the coolmini shop or by doing a google search.
If you could give the kind of size and style you are looking for i\'m sure people could help find what your looking for. Hope thi helps a bit. Gary
Just thought of another one if you don\'t mind a little work www.princeaugust.ie on here you will be able to find molds for viking minis in 40mm so you can cast your own and make as many as you want. As I said it\'s a bit of extra work but if you wanted them for a large army it would be an inexpensive way to do it.
