No way we can give you a meaningful answer- sort of like "What is a Ford Truck worth?" Value of ANY gun is based on make, model, and condition. The Tranter was a British revolver, and may likely be an antique firearm (Made prior to 1899 is the legal definition of antique firearm in the US) This will require an hands-on evaluation by someone knowledgeable in antique European arms. Your best bet may be to visit a gun show in your area, where dealers and collectors are gathered in one handy location. Wish we could help more- sorry.
