Thanks fellows.
The sculpts above are ex Black Hat, now Fighting 15s and sold under the Gladiator label. Unpainted the heads look too big and the arms too short. The same dollies were used for their Sikh War range. The League of Augsburg clothing style masks these flaws and on the plus side the figures have a lot of detail. Once painted I think they come up nicely.
One of the pleasing things about this project is that Essex, Irregular and Gladiator figures work together nicely enough.
