Copplestone Castings have released a pack of 15mm Barbarian miniatures. From their announcement:
A pack of 15mm fantasy Barbarians is now available: FM1 Barbarian Heroes - 10 character figures. I decided to use 1/100 as a base scale. This means that 6ft tall Barbarians come out as an average 18mm to the top of their heads - any normal humans I make in the future will be mostly slightly smaller than this.
