Welcome John.
There is a bolt action sub forum here you can access through the main forum page.
Many true experts here can help you. You can provide pictures through a 3rd party hosting site. Most use Imgur.
I will say a totally parked rifle is most certainly a rebuild though.
Edit to add: The "How To" sub forum has specific instruction threads on sizing and inserting pictures to your thread in the bolt forum.
Also this site is a good resource for looking up serials, barrel dates and correct parts for your your '03.
