You are correct 13 gauge is .710, however 13/1 and 14/1 are not the same as 13 or 14 gauge. I have several references that show 13 over 1 as being .719, unfortunately I cannot find a reference for 14 over 1 on a 12 gauge.

Tonight I will dig more.

From the Hallowell bore size chart:

12 .729"
13 .700"
14 .693"
15 .677"
16 .662"

Not sure what that would make 14/1.

From Greener, the gun and its development p.301 14/1 is .701

However another article I found online:

“ With a double gun, even one in original condition, the two barrel sizes may not be stamped up the same. With one that has been worked on in the bores and reproofed they may be quite different and even carry proof marks from a later period marked to another system. A very early breechloader marked up 12B 13M means that the main bore is gauged at 12 and the muzzle is gauged at 13, so it is choked. Not for ball was also an old way of signifying a choked barrel.”

https://www.shootinguk.co.uk/answers/technical-answers/explaining-shotgun-bore-4610.

Bottom line: I cannot answer the meaning of the 14/1 with 100% confidence without being able to measure the bores and they may have changed enough over time to blur an answer.

Thanks for the feedback guys.

Yes the 14/1 is puzzling. I'm used to seeing 13/1 on most of the old British shotguns. I took the action off the stock today with a view to refinishing the woodwork. I had quite a battle removing the butt pad, the bottom screw took some effort.

The action appears very nicely made. I'll post some photos if there's any interest.

Cheers

Graeme

14/1 =.702". This stamp means at time of proof it would accept a .702" gage but not accept the.710" one. It could have been anywhere in between. I have a Birmingham proofed W Richards made by J P Clabrough which has the bore marked 14. It has pre-1887 proofs though, so "Tween" sizes were not used then so could have been anywhere from accepting a 693" gage to not accepting a .710" one. It is currently just under the .710" size by a thou or two. I cannot, of course, prove it has not been altered over the years but it was my Grandfather's gun & I do not believe it was done so after he acquired it, but do not know when that was. I don't believe he bought it new.

Other than the what,the why is far more interesting. Why would a barreler bore a tube to 14/1 or 14. What is gained?

I believe the theory was based on fiber wads getting good tight seals ultimately yielding good velocity. At least that is 13/1 theory, 14/1 not sure

I have 7 Boswell Bfs from that period and they are all different. Wonderful guns.
