I bought a Winchester Model 12 in 16 gauge today. It has a adjustable choke/compensator that I can't find much info on. It's numbered 15, 20, 25, 30 ,35 and 40 around the bottom of the choke.
I found the patent from the # on the choke. But using the name on the piece, I can't find a match or any other info. I'm usually pretty good at finding things but my google-fu is weak tonight. Here is what I have.
