Mr Snyder; Thank you for the information. Your post started me thinking that maybe I wrote down the wrong letter so I made a trip back to check the gun once again. It is a F, it also has the #4 on the left barrel flat and the #2 on the rt barrel flat. Being this gun was made in 28 will it be chambered for 2 1/2 shells? And what is your opinion of the smokeless powder steel barrels. Are these good guns that I can still take out for a round or 2 of sporting clay a couple times a year?(using the proper loads of course)? Thank you again for the information.
