Please identify this rolling block

I saw this gun for sale a few years back on gunbroker, and can not for the life of me find anyone making a rolling block with such a thick octagonal bull barrel.

Looks like a modern italian made replica of a Remington Rolling block rifle.

Maybe one of these, with a new barrel and band:
