With an antique weapon, you will need to get a professional appraisal. I have seen weapons in an 'excellent' grading from this manufacturer, in 12 mm, offered for over $1200. But condition and rarity are key. Take it to a gun dealer that sells pre-1900 guns.

The answer to your question is -that will require an appraisal by someone familiar with antique European firearms, and will depend on model and condition. The Jongen Brothers revolver I have seen was an unusual "reverse break" type, hinged at the top, barrel swung up at the rear of cylinder. Have found mention of Jongen in 4 patents on revolvers, believe they were active in Liege Belgium in the mid 1800s.
