I believe you are asking about a Sears, JC Higgins C02 Air Rifle. If so, it was made by Crosman (model 180) for sears under the JC Higgins name, It has a wood stock. Mfg first in 1956-59 and then again with a die cast trigger housing from 1962-67.
In Prime 100% condition it is worth $180 but from what you say it's more like 20% condition at about $55.
