Have seen the early releases in the lead, and in a one-word summary:
DISAPPOINTING
Not helped by them being covered in white paint, presumably liberally applied with a decorators roller, but the detail wasn't great.
Most disappointing feature was the rifles were tiny compared to the figures, and other ranges - a real shame, as it would be good to have other ranges to work with. Perhaps the new releases have corrected this, but I wouldn't buy them without seeing them "in the lead" first.
Personally, i'd strongly recommend the following for VBCW:
Musketeer
Empress (Anglian miniatures SCW range)
Great War Miniatures
Artizan
Pulp
Gripping Beast - their head sets are very very useful for conversions.
Copplestone
even some Renegade will fit in.
