What is the value of a Benjamin Sheridan Corp Blue Streak .177 cal?

There are several variations of this rifle. The CB Blue Streak and the CB9 Blue Streak along with CW and CBW with Williams Peep sight. Crosman owns Sheardon and Benjamin. During the 1990's they put both name on the rifle. Later they separated the names again.

Unfortunately you did not state the condition of the rifle so no estimate of value can be given. Is it Excellent, Very good, Good, Fair or Poor? Re-post you question with the model name and condition so I can give you an estimate.
