The first Orc is a Reaper Bones miniature. It is too large for Middle Earth, so will have to do as a one of a kind champion or bodyguard type. Comparison pictures further down will show what I mean.
Conqueror Models metal Dwarves with an Oathmark metal Dwarven King.
These orcs are also Reaper Bones, earlier Bob Olley sculpts which are closer to the right size. The orc on the left has been converted to carry a proper looking spear from Wargames Atlantic skeletons set, and a shield from Oathmark plastic goblin set. The spears they start with are often bendy & like tree-trunks.

Orcs Grunt, Conqueror Models metal Dwarf. Middle Earth Orcs should be much closer to Dwarven height. Orcs as tall as humans was the exception not the rule. D&D and other fantasy systems have made orcs larger.
Elven Ranger from Reaper Bones. Even in the Bones material this was a nice miniature to paint. Plan is to have him as an elf of Rivendell or Lindon to accompany my small band of Dunedain Rangers of the North.
This is a human Ranger in the Reaper Bones material. The detail on this sculpt was really soft compared with the elf, I found it difficult to work with.
