Choke Identification

[Gumby]

Does anyone recognize this choke? It came with a 1989 Win1300 NWTF gun that I got off of GunBroker a few years back. All I was told was that it was a "turkey" choke. Any ideas? The blue markings were already there....marker of some sort. Looks like a Carlson's but that's just a guess

My guess is a Bailey thin wall . But, it does look like a Carlson

Did you measure the choke end with calipers? That might help some.

I did. Measured at .685
