Well the set name does not lie - if you want just horses then this might be the set for you.
This must be the ultimate in simple sets to review. There are 72 pieces, and they are all the same. The horses come in three colours, with 24 each in black, brown and grey. The pose is reasonable and the style of saddle and harness suggests it is most appropriate for use for 19th century subjects. It is not a brilliant sculpting job, but neither is it bad. If you have need of a large number of horses, perhaps to replace poorly made examples from other manufacturers (Airfix with their separate bases spring to mind), then this set offers something unique.
