[TARNATION !!!]

Both Serial Numbers show the same info in the book.

Grade: D2 = Grade 2 with Damascus barrels
Action: Underlifter
Extras: 0
Stock: Pistol Grip (not capped)
Gauge: 10
Barrel Length: 30 inches

It appears the struck out SN is only on the fore end iron. Subject to guessing what might be behind that - an earlier order for a two barrel set that was cancelled for single barrel set so the already stamped fore end iron was restamped for this gun?????? Other thoughts?

Bolsters are engraved but not sculptured

The pictures are nicely done and appear to represent a gun matching the information in the ID&Serialization book.

The gun looks like it needs a lot of TLC and smith attention prior to putting back into service (if the barrels are okay)
There are rust issues
The stock head appears very dark possibly indicating a lot of oil in the wood
The barrels appear to be off face
The Dogs Head Butt Plate is worn very smooth, indicating a lot of use - I LIKE THAT - Maybe your friend could tell us a few hunting tales associated with this gun.

Cheers,
Jack
