Unusual Rolling block action ??

Anyone know anything about this action. Belgian proofs. I recently bought this one with a 28 ga barrel.Attachment 37

Thanks, Greg

hello brayhevan not sure if i am right on this but just from the pic i am guessing that what you have is a husqvarna //// not sue of the model but they did make some in the mid to late 1800s based off the remington design // if i had more info on it could give you a better gues/// a word of caution do not shoot mordern ammo in it and have a gunsmith check it sply the chamber length if he declares it ok for firing use black powder only
