I have a Black Powder Only Hand gun Made in Italy, Caliber 44
What is the value?
Revolver?? Single Shot?? Flint?? Percussion?? Uberti?? Pietta?? Pedersoli?? More info is needed. That's like saying " I have a car...what's it worth".
The more info you can provide will get a firmer guess. If you can local a manufacturer's name, give a good description as to style and condition it would really help.
Hope that helps
