Curved M and others

Hi everybody. This printed image is from an era before easy often digital printing and digital fonts (at least here in my country), 1990 exactly. To add more dificulty, this version is the worst produced, some error was made, adding to much or less light in the process, resulting in darker images and fonts, manny bleeding/gluing at each other, so this print don't is accurate /not faithful to the original outline of the font. Pay attention to U, M, N, A, R, X. Yes, I tried some characters and then some words, but nothing.
