The Crosman model 66 Powermaster BB rifle was made between 1983 and 1986. In order to get and estimate of value you will have to state the current condition of the rifle. Is it still working? Is it in Poor, Fair, Good very Good or Excellent condition. without more information it is not possible to give and estimate of value. Re post you question with this information and I will try to give you a reasonable value.

Colman did not make a model 66, Crosman did. In fair working condition it is worth around $25-$35.
Both Crosman and Daisy made air rifles for Sears under the JC Higgins name. My catalog list the model 126.2831 as a Crosman model 180. I believe your model 126.2830 is also a Crosman model 180. The 180 has almost no forearm, a long barrel. It's a single shot .22 Caliber bolt action and is driven by a C02 cylinder. It was made between 1956-59 and again from 1960-66 with some slight changes. If you want an estimate of value please give a current description of the condition it's in. Is it in Poor, Fair, Good, Very Good, or Excellent condition.
