Grenadier Models went out of business in the mid-90s, but their models are still produced to this day by Mirliton. This range incudes almost everything classical fantasy has to offer, including Half-Orcs, Hobgoblins, Goblins, Orcs, Trolls and Giants.
Above you can see some of the Goblins in their range. Interestingly they still sell the Grenadier Giant, which sometimes on eBay described as a rarity…
They also have a lots of Trolls and Big Orcs, which if you compare the price of Trolls and them should be almost as big. Left: a Big Orc, right: some of their War Trolls.
Mirliton have a big range of oldschool Greenskins. With Goblins costing below 2€ a model and Trolls just over 6€ it is certainly one of the more cost effective ranges of metal miniatures out there. You can buy the shown models and many more on Mirlitons website and can also find them on Facebook. All pictures shown above belong to Mirliton.
