Just to throw some numbers out from a quick eyeballing with a tape measure...
1895 barrel has 12 square threads per inch.
1899H takedown barrel has 12 square threads per inch.
Westfield 99F barrel has 14 V threads per inch.
Savage 11 barrel has 20 square threads per inch.
I know nobody cares about the last one, but it was laying there so I measured.
