Ok now that I have my mounts back from Africa I have some questions. First is does anyone know what the oily like substance is on my shoulder mounts(smells like a solvant or an insecticide)? Is it something that can be washed out? Second is these are the first skull mounts I have. I want to mount them to a plaque. Prob in the shape of Africa. Any recommendations on ways to do this? Just brain storming now. Finally any thoughts on how to attach the horns to the skull since they come detached crime the skull? Thanks in advance for the help!!
