The PDF Spreadsheet for the GCA Journal, from Volume 1-1 through Volume 37-4, Fall 2023, is posted and downloadable.
Go here to download: https://www.nicolausassociates.com/gca_journal.htm.
Below is a sample page of what the spreadsheet looks like.
Nicolaus Associates is a publicly available clearinghouse for U.S. military small arms technical information, and militaria, including diagrams, technical manuals, field manuals, graphic training aids (GTAs), posters, prints, PS magazines, lithographs, blueprints, art, militaria, and other related information.
Start here to learn more: https://www.nicolausassociates.com/index.htm. All available information has been vetted and released to the public domain through either the National Archives or typically the Department of the Army.
Nicolaus Associates does NOT ship overseas.
Finally [and for post-Christmas gifts], a note about coffee mugs. Please email me. Include your full mailing address and phone number along with the number and type of coffee mug you are interested in, e.g. M1 Garand, M1 Carbine, M1911A1, and / or M14. I typically order for family and friends - however - there are very few "spares" I have left over from Christmas.
