Any competant smith can clean and repair that old winchester. A restoration can be done without destroying the weapons value if it's condition is such that there is no collector interest remaining. The M67 was one of the most common single shot 22 rifles Winchester made, and many of us learned to shoot with one. They are fairly common in most variations. I restoration is desired I have heard wonderful things about about Doug Turnbull Restorations. Still if this rifle holds memories for the intended resipient, I would think long and hard about 'restoring' it. A good cleaning and repairing it would probably be best..
