Crossman 100 Scope Mount

I have a Crosman 100 and have the idea that I would like to try a scope on it. So has anyone ever seen a mount for one. Or does anyone have an idea about making there own.

I think I saw some where that some one machined a mount and clamped it to the barrel. Sorth of like the Sheridan mounts. The 100 has a big heavy barrel and I would think this style would work. Anyone have any ideas??
