This is not likely to be a very satisfactory trap gun. Trap is usually best shot with a more or less purpose built gun. Be sure the lady understands that not all guns perform all tasks well. She might get frustrated shooting trap with the gun and sell it way too cheap as just an old gun. Take a careful look and see if you can determine the gun's suitability for this lady to shoot trap with. If it is in the 6# region, she will need really light loads, most likely.
