dont expect much. its all up in the air because basically you have collectible items that dont compare to whats made today.
however in my area, youd be lucky to get 150 for the top break, namely because its not made anymore, sw wont service it, its a 32, and the 150 would be dependent upon a letter from mr jinks that shows the pearl grips are from the sw factory, that the gun itself has the original box, manual, sales reciept that corelates with the jinks letter, and that you can prove its never been fired outside the sw factory.
other wise dont expect more then 50 for it.
