Mod. 3000 Shotgun Multi-Choke Questions

[Goony]

I have a Model 3000 Multi-Choke barrel (12 ga.), but no original choke tubes. I am aware that there is nominal interchangeability with Winchester, Browning Invector, and Mossberg 500 tubes (the latter being flush fit).

My questions are, what sort of configuration do the original S&W choke tubes have? Are they marked with the Smith & Wesson name or trademark? Can maybe someone post a picture of one here?

The choke tubes has a knurled portion the same outside diameter as the barrel that extends about 5/16" beyond the end of the barrel.
No markings other than Full, Mod or Imp Cyl.

12 gauge tubes, carrying pouch and spanner wrench.

Give LSG, Mfg|Gun Parts|Warranty|Gunsmithing a call, they bought all the "Made in Japan to Smith and Wesson Specs." gun parts and have the choke tubes listed on their website.
CDNN Mossberg Choke Tubes/Tools has some Mossberg extended choke tubes that may work.

Thank you, sir. They (and even the wrench) look just like the Winchester type.
