Stick it on the bay as a Star Wars scope and you may well get £100 plus. Its missing its caps.

As an air rifle scope then £35. As a Star Wars prop £100 to £200 depending on condition. Yours is the clear perspex day example so more desirable than the day/night misted version which used to be more expensive.

Many have cracked lenses which the Star Wars guys don't worry too much about. They even print copies.

Certain 4x20 scopes do well too as Star Wars props.
