I have several of that vintage Tasco World Class TS scopes. They always track and are very rugged internally....use them a lot for testing.

While I haven't had that exact scope apart, I have dug into a few others. This is a similar vintage Tasco World Class non-TS series scope that I've robbed the ocular piece from. The reticle cell is held in place by this plate that's retained by these three screws. Remove the screws, remove the plate and the lens cell is free. Not sure if yours is exactly like this or not.

Just take the ocular off and take a peek. Don't worry about any gas stuff. Anything that was ever in there is long gone. The reticle cells are extremely fragile....be careful and handle them only as little as needed.

Sometime, the cells are held in with little spanner rings. That's how this Sightron was when it came apart to be locked locked and the w/e assy. removed.

Take the ocular off and post a few pics...we can likely walk through it at that point.

Good shootin' -Al
