I bought this musket from Czernys auction. If you have viewed their auctions you know they will give just a couple pictures so you buy without being 100% sure what you will get (unless you go visit Italy to see it in person). When I first got it, I thought it was a fake. I had never seen a barrel that was octagon to round and then back to octagon. It also bothered me that there was no ramrod channel. It didn't help any that there are obvious modern, and incorrect, restorations (butt plate, rear sling swivel, modern rear sight). The trigger guard is appropriate in style but has modern screws. I asked a few friends online that have had more experience and they told me that the oct-round-oct barrel was a cheap way to balance the barrel without the extra work/skill to swamp an octagon barrel. I was told that this was likely a commercial hunting musket (think stereotypical fox hunt on horse, not much reloading in that scenario) and this is the reason it does not have a ramrod channel. It probably never had a butt plate until the wrong one was added in modern times. Thought I would share since it is such an oddball.
