Remington New Model Army with Round Barrel

[drjldavis]

While attending the Tulsa Expo gun show I came across a highly engraved Remington New Model Army marked Replica Arms.  It had a round barrel instead of an octagon barrel.  Sunday I received an email concerning an up coming auction and low and behold there was another Remington, not engraved with a round barrel.  Has anyone else run across any Remington New Model Army revolvers with a round barrel?
