The condition hurts that value but it's not to common of a pump. The rarity may help a collector overlook some of the damage but without the skins it would be a hard pump to complete. If you are a pump guy I would keep it, if you heart is in globes or signs I would advertise the parts to a pump collector.

Could you get a picture or two for us to post?
