good job helping her out!
you should post a picture of it... upload a picture to photobucket or imageshack then use the image code to post it on here.
It might not need anything other than air tool oil ran though it and maybe a few o-rings?
odds are it doesn't have a velocity adjuster on it so that is something you should look into if your wanting to play with it.
to bring it up to date,a valve tune will give you more shots per 12 gram.
air it up and give it a try!
