while the thumbhole stock is nice, I purchased one a few years back, brand new for $149.99 And there was a store selling the version that had the thinned out hunting stocks once for $75.00 . I have one of them as well now. So you can decide what it is worth.
If this is brand new in the box it might be worth that. They are good shooters with about 85 grains of powder and a good bullet.
