Definitely not my best but right at the top as one of my favorites would be . . .
My early A grade, 12 gauge Fox, SN 7983 with 28 inch Krupp barrels choked IC and Full.
I got it from Glen Appleby of Galeton PA in September of 1968 for $175.00.
Shot many ducks and geese with that gun when you could use lead shot. It's had around 15,000 rounds thru it in the last 10 years shooting "at" Sporting Clay's.
That's the top gun pictured below.
Lately tho, I've taken a liking to my newly acquired, unmarked as to maker, grade and serial number but looks to me to be an office sample or lunch box gun.
In appearance, it looks like an early B12 Fox with some added, nicer features. That one is the bottom pictured gun and the two pictures below that. Note the absence of serial number, grade, patent info, etc.
