I have seen a rib like this only once, but not on a Parker. A local collector dealer asked me to look at it and give them my impression since they had never seen one before. It was a medium grade English double (well known maker but I just can't remember). It was in .500 BPE, hammerless, late 1800's. The rib looked just like that. The reason for the question was that the entire surface of the barrels had the same finish. It ppeared to be a rolled knurling, such as you would do on a lathe with a knurling tool. It was very obviously knurling and not a cut pattern. The thing that made that amazing was that the pattern was applied lengthwise of the barrels and blended radially so that there was no appearance of bounary lines between the bands. It appeared to be a perfect knurling job of a tapered cylinder. To this day I have no idea how it could have been done.
The term chased used in the letter would now mean some sort of recutting, deepening or cleaning up operation. No idea as to the meaning in those days. That could be a definition which would help reveal the technique.
