Hi Dennis, the scope mount looks exactly like Greg Lundys Ballistic Enterprise mount.Are you working with him? I have 2 of those mounts for the older model C Sheridan flat tops that he made.looks the same but fits the flat breech. A friend ordered one from him for like $69 and he never sent it to him.In fact he disappeared from the airgun community. I know all this is weird and people have problems in life. Anyway will you eventually make up some for the older Sheridan and b enjamin rifles?
