Who can ID this choke tube?

[Gnome75]

I bought a new to me shotgun and it has this choke I have not seen before. I looked around and I think its a win choke.

Can some one tell me what it is? I am looking to get some tubes between cylinder and improved cylinder.

It is out of a E Rizzini if that helps

I don't think that is a Winchoke from what I recall.

E Rizzini interchanges with LC Smith style chokes.

Not common ones like Win choke, rem choke etc

Thanks for the input. I found some from a british site. They interchange with Lincoln as well. These are a rare choke
