Good shotgun, slightly high price, unless.....
Ask the shopowner to take the stock off. Look as the receiver and see if there's rust. This may be one of the notorious "Salt Wood" guns. If not, follow your heart. If you want the thing, buy it.
For those that can shoot them, the A-5 L comes in a trifle heavy for upland work, but lots of folks love 'em.
A small suggestion if you buy it. Take it to a good smith or shop and get a new set of springs and friction rings installed. Price is minimal and my smith calls it the 10K Round Rebuild. Enjoy...
