A:
The number on the back of mine reads Ref. E67008U. The rest is printed line-by-line as follows; 11 3/4"x 8 1/4", Ruled/Margin/Perforated, Premium 24lb, 140 Pages, SAP# 714015. According to the Bn'R Website [go to Site found on back cover] your Ref. # B79019 is indicating a Wire-bound Notebook "Hardback" version, same specifications otherwise I believe but this one is called a "Soft Cover" wire-bound. I prefer the "Soft" for carry, it's lighter, covers are much thinner yet the Poly makes them very durable, Poly covers themselves wipe clean easily inside & out. If you store your notebooks on a bookshelf, then the "Hard" covers would most likely be preferable as I'm sure they'd stay upright or on-edge better than a flimsy Poly, if not the Poly is really tough for as thin and lightweight as they are. The paper itself on mine has a left-side margin on both front & back sides of each page, pages perforated, not sure of the "Hard" version since I don't own one in this size. I hope that helps.
