Be VERY careful, if it has the original barrel - those old ones have a habit of getting fatigue cracks adn blowing out. Painful.
If original, get a decent gunschmidt to check her out.
Other than that, yeah - great guns. We used a set of Parker-Hale tweaked 303s in the rifle team at school, and it was possible to get a 10-inch grouip at 500 yards with service ammo. No bench, no bags, just what you Yanks call a Hasty Sling.
Good times...
