In NEW condition it's worth about $300 (it's not a good seller)...
I believe you are asking about a Sheridan .20 cal (5mm) air rifle. They started to make this rifle in 1949 and stopped in 1990 ( sheridan sliverstreak model ) During the 1990's the name changed to C9 sliverstreak and C9 bluestreak. The value is determined by the current condition of the rifle. You did not give any such information , therefor I can not answer you.
The Sheridan Blue Streak air rifle uses a 5mm pellet. This is about .20 caliber- larger than the .177 pellet, smaller than the .22 pellet. I have been able to get these at Bass Pro Shop. There are also at least 3 lots of them for sale on Ebay right now. Only the 5mm/ .20 caliber pellets will work in your rifle- do not try to substitute anything else. P.S. Have had one for years. These are extremely good air rifles- very accurate, very powerful.
To install the bolt in a 5mm Remington rifle, first ensure the rifle is unloaded and pointed in a safe direction. Pull the bolt handle back to its rearward position, then align the bolt with the receiver and slide it into place. Once fully inserted, push the bolt handle down until it locks into the closed position. Finally, check the action to ensure it operates smoothly.
