Thanks for all the comments. A few more questions...

1. What is the significance of " 1-1/8 " on the barrel flats? Obvious that was the nitro proof shot weight. Does it tell us any more?

2. What is the significance of " 1/31 " on the barrel flats?

3. I didn't see any length designation on the barrel flats. Should it be there?

4. Is a well-restored moderately engraved Birmingham BLNE 12 gauge worth $3k? If I tired of it, would it be difficult to sell for that amount?
