Reconsider - 1939 Uncoprighted Catalog - Can it now be copyrighted by me?

I have an uncopyrighted Lenox Incorporated company catalog dated 1939. Data includes 3 thousand shapes and 4 thousand decorations of the first 50 years of Lenox. There are no copyright symbols only the company name "Lenox Incorporated Trenton NJ" at the bottom of each page. This historical data would be well received by Lenox collectors.The catalog includes alternating pages of photos and data along with the 1939 prices.
Additional information
This work was obviously published without registration or copyright in 1939. It apparently received a fairly wide distribution. Notice the use of the the words dedicated and at your disposal. Cover letter inside declares. "To our many friends who have helped us during the past 50 years to build our business, both by their patronage and counsel, and to those whom we hope to be of service in years to come, we dedicate this volume of Lenox achievements.
Even though incomplete, we trust this partial compilation of our three thousand shapes and four thousand decorations, which have been developed during the last half century will be of value in our business relations.
From time to time, additions will be made of new shapes and designs, as well as old ones not as yet included in this volume, so that you will have at your disposal a complete catalogue of Lenox productions. Lenox Incorporated H.A Brown President Oct 20, 1939"
Research - Uncatalogued with copyright office, unlisted in renewals.
LAW -Works published in 1939 without registration or copyright were injected into the public domain. I understand that Lenox could try to claim it was unpublished, for internal use only. The cover letter pretty well refutes that claim.
Remember the laws for PUBLISHED works were different in 1939 than for today.
Now my goal is to copyright my electronic rendering of this material and distribute to collectors as reference guide. I would appreciate any suggestion on keys areas of consideration.
I welcome your arguments.
