Thank you Walter.  Yes, the right barrel is marked as you indicated.  This is a 16 gauge/28" gun in high condition and I'm impressed at the quality of the wood, fit & finish in this Field Grade gun.  
I enjoyed speaking with you while at the Southern and look forward to seeing you at the NE Side by Side = May 31 to June 2.  I'm also sending you a PM on something we discussed.  You're welcome to bring as many ringers as you'd like to the Fox Collectors' Bo-Whoop Long Range Championship and our new (as yet unnamed) vintage SBT event at the Northeast SxS.  Just a reminder to all, the B-W Championship isn't limited to A H Fox shotguns.  Any side by side 10 gauge or smaller may be used.  First place honors and purse goes to the high gun.... last year JD Shank won with 5 ex 10 using a 12 ga W & C Scott Pigeon gun.  And the high score with an A H Fox shotgun is named our Bo-Whoop Champion; Tom Wyraz took the honors in 2012 with 4 ex 10 using a 12 ga X/HE Super-Fox.
I help to set and proof shoot the B-W targets, also run the Championship, and thus I don't compete myself.  But I did shoot the targets last year with an Ithaca NID Super Ten.  And that Ittaker (as they are sometimes called herabouts) made a pretty good showing.
