Steel shot special ID?

[Jared V.]

So a 2 3/4 and 3" chamber marked gun has to be either a sporting clays classic with the choke tubes or a steel shot special with the chrome lined bores? I'm a bit confused as I have seen some 12 guage repros with the 3" marking on the barrel and not advertised as either of the above. I need some clarification on this.
Thanks in advance,
JJV

...and then there was this Repro brochure that lists 12 and 20-ga. 28" guns as available with either 2 3/4" or 3" chambers.

It also lists the 28 gauge 3" chamber as an available option. Repro paper is notorious for oversights. However, some "oversights" may have been considered for production but not actually produced.
