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.
You have given me all the information except the model. Sheridan has several different models at different prices
The value of a benjamin sheridan 392pa 5.5mm 22cal air rifle is $185
The Sheridan Silver streak air rifle was made from 1949 up to the 1990's after that it became the Blue Streak.
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.
Crosman owns both the Benjamin and Sheridan line of air guns. See the link below for the Marauder parts list and the customer contact page for Crosman ( They sell parts for the PCP rifle.)
