Mike: the top is 2 Iron
Crolle', Damas Anglais, English Two Rod, Hufnagel, or 'Oxford'
The middle is 3 Iron as above
The bottom is of course Twist
I'm thinking this was probably a Salesman's Sample Rod for the 1878 hammer gun rather than the 1883 hammerless, which had nicer damascus
Three Iron 'Turkish'

Paul's gun with 'English Best' Four Iron 'Turkish' similar to what would be found on D grade Parker and Remington guns and Baker Paragons

I've added those pics to the 'Colt and Remington Damascus' PictureTrail album
