Fox Collectors

I inherited a AH Fox shotgun. Serial # 28511 A model
Barrell info Chromox fluid compressed steel, made by AH Fox DJN Co. Phila Pa.

Engraving on side has AH Fox in a scroll pattern.
Patent dates: Aug 16 04,Aug? 05,Oct17,05,Jan 16 06,May 11 09,May 2 11, June 14 ?.

Any information on this gun will be appreciated.

Thanks, I used that web site to locate the information. Now I would like to know what it means. For example, where does this gun rank in the Fox hierarchy.
My gun is in excellent condition, the barrels are still as blue as when the gun was new.

The A grade Fox is the entry level graded gun. They are one step above a Sterlingworth. They are a very common and handsome gun. See this link http://www.foxcollectors.com/ah_fox/con ... fox_2.html
If you would like an evaluation of your gun please post good pictures. Your gun dates from early 20's.
