I have had these for a few months for the trial army book project and they are very good models indeed
Would you be able to post a photo comparison of the Anvil Dwarves next to the GW Dwarves?
If azrael71 doesn't beat me to it, I'll have them up on
my site in a few weeks (about to leave on holiday).
Also, remember that the plastic BoFA dwarves are smaller than the metal BoFA and Warmaster dwarves. A great comparison would show the Eureka dwarves next to all three.
I have one Eureka chaos dwarf (came with an order as a sample). If the anvil dwarves are the same size, they should be perfect.
