In the UK the Old Glory line of Orcs, Elves and Dwarves were sold under a "
ghost Miniatures " label and can be still found in 2018 from
Graham's Wuerkshoppe of Newcastle. I do not know if the shop owner takes mail orders, that is something one would need to ask them about. Expect to pay about £5 for an unopened pack of about 8 foot soldier orcs or two wolf mounted orc cavalry models.
I took comparison photos of the Old Glory/Ghost Miniatures orc models with their Citadel and Marauder counterparts, please see the attached images. In my own opinion they are a good match sizewise with the other orc models of the same age. Stylewise they are somewhere between the early 1980s Citadel and Ral Partha orcs and the more modern late 1980s Citadel and Marauder orc models.
