What is the age of a Sheridan c series 5mm 20cal rifle serial number 370862
It was made in 1983
The C9 was discontinued in 2012. But I think yours is much older. Sheridan had a very unusual past ( too long to go into here) I suggest you go to the CROSMAN web site and give them the serial number and ask them for information on you rifle. Call them. Crosman owns both Sheridan and the Benjamin line of airguns
A short history. Benjamin air rifles and Sheridan air rifles once were separate companies. Sheridan developed the C9 20 caliber series of rifles. Benjamin bought Sheridan and continued to make the C9 20 caliber series rifles. They also made a .177 and a .22 caliber C series rifle called a Benjamin. Crosman bought out Benjamin (in 1992) and decided to continue making the C series. With the name Sheridan on the .20 cal rifle and Benjamin on the .177 & .22 cal rifle some rifles also had the Crosman name on them. ( confused enough?) During all this confusion and name changing the C9A came along. I have 4 reference bluebooks on air guns and not one of them can give me a date for the C9A, But Crosman has a web page that list manufacture dates by serial number for Benjamin and Sheridan. (See the link below) when it opens scroll down to the Sheridan dates. (the first part is all Benjamin) Hopefully you have the serial number and can match the number with a date of manufacture.
