Ykreol had a wonderful, extensive series of sets, YKRIP
Sadly Yves no longer seems to be making them. Perhaps he could be encouraged again, or others could buy the moulds?

Newline design have 20mm casualties for most periods and armies, they work with 1/72.

I could look them up myself (and probably will...), but what medium are Newline figures, metal, plastic, or resin?

Just ordered some of their figures today....all appear to be metal, but are very reasonably priced.

Also, there are some nice casualty figures from Speira Miniatures you should check out as well.

Working on a horse casualty for ACW and Napoleonic wars, but will take some time, eventually it will be sold under the Speira label.

Great news indeed!
