Its here and I like it, though I would say that. What makes this genuine to my rather uninformed eye when it come to bronze casting. Is the general softness to the metal surface no harshness to the detail. Also the same with the patination, nothing harsh and recent to jar on the eye. The wax work although simple and some what rough and ready, there is a subtle attention to detail. I think it is most possible that it comes from the Cross River region. There were many punitive and anti-slavery British military expeditions in the region at the turn of the 19-20th century. Here are some more pictures.
