Grenadier Models
For a while, this was the company that produced D&D figures. Their willingness to branch out lost them the license. But they put out a lot of figures including a wonderful range for Call of Cthulhu and a 25mm Traveller run. Like so many companies they started with several historical ranges in 25mm. These were initially not favorites of mine. The figures seemed fat and the details poorly executed. But as the years passed and RPGs took over, quality improved significantly. This seems to be the case with many manufacturers, either developing their own abilities or hiring on quality sculptors.
