I own A-Grade 16-gauges in both 30-inch





and 32-inch --











From fifty years of playing with Ansley H. Fox doubles, I'd say that 28-inch barrels are far and away the most common length in 16-gauges, followed by 26-inch and 30-inch being about the same and 32-inchers least common.

I searched through the first 2000 graded 20-gauge Ansley H. Fox records and only found 47 32-inch guns, so they are fairly rare!!
