Contact info for K.C. McDonald, author of "Forgotten Federal ‘Generic’ Garments"?

[DrMike]

I am completing an article on the Federal Infantry and Signal Corps uniform jacket, and would like to contact K.C. McDonald for permission to use an image from, and obtain the correct citation to "Forgotten Federal ‘Generic’ Garments: Part 1, the Federal Infantry Uniform Jacket & State Issue Shell Jackets"


I'll be grateful if someone could furnish that information!
