If it was given to you by a old friend i take it your no looking to sell it ?. The guns what i would call in a used condition , but then i of think airguns as a tool for getting the job done and no as a ornament so a spot of blood ect on the barrel will cause rusting but it doesn't affect there use or aim , if you want to sell it see it as a project then that gives somebody the chance to clean it up if they want
