The Savage 67 was a good quality utility-grade pump gun.
Like all Savage guns, it was well made.
The things to look for are the same as on any used gun:
Rust, corrosion, and pitting any where but especially in the bore.
Look for excessive wear and tear to any parts, and look for any signs of alteration or "Bubba's" handiwork.
Look for cracks in the wood, either around the area where the butt stock joins the receiver, or around the pump handle.
Check all functions of the gun (safety, disconnecter, hammer stays cocked, trigger pull isn't too light, etc) for signs of wear, alteration, or damage.
Check the magazine spring for rusted or weak spring, or rust in the tube.
Check pins and screws for signs the gun has been disassembled. This is often a sign someone unqualified has been inside doing God knows what.
Pump shotguns are usually dirty ranging to filthy inside, since people seem to think they don't need to be cleaned.
The "look out" is to be sure there isn't rust or corrosion under the dirt, especially in the bore or chamber.
Chambers especially can corrode when used with modern plastic shells.
In general, a used pump shotgun is often dirty inside, with worn exterior finish on metal and wood, but is often in excellent mechanical shape under the crud.
