I was at the antique arm show in Vegas this past Friday and Saturday. There was a dealer there who had a first model 1873 rifle with a round barrel that had been restored to like new condition. I believe he was on row E. I didn’t get his contact info, but would like to get in touch with him if he is on here or anyone knows who I’m talking about. If it helps, he also had a second fully restored rifle; I believe it was an 1876.
