Good morning Kevin.
Chokes Marked and measured Full/Mod. They were mis-identified by the seller.
Regarding your description of the desireability of the Long Tang I would add that the "Bean Counter"
who instituted the Short Tang and the Flat Knob programs should be horse whipped!
The missing parts referred to the new barrels only.
Everything having to do with the forend and everything having to do with ejectors.
And a silver front bead.
You're probably right on the IC / Skeet chokes.
Thanks for your input.
