nr davis and sons hammerless double
 

I have a nr davis and sons double barrel.
There is no serial number only the number 36 on all metal parts. Im guessing these are assembly numbers?
The problem im having is the bore measures .660 and .661 as best as i can measure.
That makes this double a 14 guage and i cannot locate any info on a 14 ga made by them.
Im looking to see if anybody out there knows anything about a 14 ga nr davis and sons double
Thank you
Glenn

The nominal bore diameter for 16-gauge is .662". So, you have a 16-gauge.
