Well, since you have not been able to provide a picture, or even a good descriptrion, it is pretty difficult to say what you have/had.

First, a Jukar gun is not an antique.

But, AFAIK, Jukar made only muzzle loaders that in a broad sense were "replicas" of muzzle loading antiques. But some were not replicas in detail of any specific antique model, so it depends on the actual wording of the law whether a given gun is a "replica" or not.
