I'm a noob and I've got a sister whose husband passed and left her with a collection of guns. I'm trying to help her determine the value of the guns she's selling primarily a model 39-6 (Lady Smith) and a AirLite PD. Both are around 20-25 years old and both chambered in .38. Any help would be appreciated. I've seen plenty of asking prices online but not very many actual selling prices. Thanks in advance.
