It all depends on the condition of the rifle. It was made between 1940-69. State the condition of the rifle to get an estimate of value. The box and instructions will increase the value by 25%.
I know of NO Co-roman air rifle. Please provide more details. Do you mean Crosman 180 air rifle?
This model 310 was made in 1957
It would be worth around $105. This model was made from 1940 to 1969. If you have the original box it is worth 25% more.
Benjamin ( who is owned by Crosman air gun) recommends 10 pumps. Over pumping may damage the rifle. You can still get the owners manual for this rifle for free. Go to the Crosman link below and click on "Download a manual" at the bottom of the web page, then click on Benjamin and locate your rifle.
The question can not be answered without knowing the maker name.
You didn't state the condition of the rifle so no estimate of value can be determined. It was made between 1969-92
Blue Book of airguns says "typically between $150-$200 price range."
