These shotguns are starting to show up more in the U.S. They're basically a SBE I. I've even heard the parts interchange but I can't verify that. There are a lot of them on Gunbroker fairly cheap for an Italian job. Some NIB for under $900. You can get them with a 30" barrel which I would like. That's what got me interested. Does anyone know what the choke tube threads are or have seen them in person? I'm wondering it it's the Mobil Choke which I have a full set of aftermarket chokes which would be another plus as volunteering for a guinea pig.
