Definitely some old Grenadier in there. But also many figure lines unknown to me, e.g. the different Escavalon armies, the Armoured Orcs, the Arcana range. Some of them could be earlier Grenadier from the 80's.
To my eye, the old Grenadier sculpts look good, the others less so.
Looks like a struggling company that grew out of a club & a rules project. Wonder how they got the licence to produce those Grenadier minis - if they own some molds, or if they actually buy the minis from that other British company doing old Grenadier?
