If you wish the seam weren't there take a look at the Rizzini BR550.
It is Pianni Fissi - no Mono Bloc Seam. I also prefer this look.
Thank you for pointing that out.
I have a B. Rizzini SxS imported and marketed by WLM made to their specifications as 'Upland EL SxS'.
It too has an invisible barrel/mono-bloc joint. I never thought it was anything but a very well done mono-bloc and had never heard of 'Piani Fissi' which apparently involves some kind of welded joint before barrel striking.
Mine was made in 2007, so they have been doing this for some time.
