Ask the question here.
This is what you will need when you ask for a value. Who is the Manufacture of the gun? The condition of the gun, (Poor, fair, good, very good, Excellent) The model number. Does it work? Describe it.
Then someone might be able to answer your question. Too many question do not give any information. Don't just ask. What is the value of my 22 gun? As you can see this type of question gives no Information about the gun, so how can anyone give a value.
